ANSTO Publications Online

Welcome to the ANSTO Institutional Repository known as APO.

The APO database has been migrated to version 7.5. The functionality has changed, but the content remains the same.

ANSTO Publications Online is a digital repository for publications authored by ANSTO staff since 2007. The Repository also contains ANSTO Publications, such as Reports and Promotional Material. ANSTO publications prior to 2007 continue to be added progressively as they are in identified in the library. ANSTO authors can be identified under a single point of entry within the database. The citation is as it appears on the item, even with incorrect spelling, which is marked by (sic) or with additional notes in the description field.

If items are only held in hardcopy in the ANSTO Library collection notes are being added to the item to identify the Dewey Call number: as DDC followed by the number.

APO will be integrated with the Research Information System which is currently being implemented at ANSTO. The flow on effect will be permission to publish, which should allow pre-prints and post prints to be added where content is locked behind a paywall. To determine which version can be added to APO authors should check Sherpa Romeo. ANSTO research is increasingly being published in open access due mainly to the Council of Australian University Librarians read and publish agreements, and some direct publisher agreements with our organisation. In addition, open access items are also facilitated through collaboration and open access agreements with overseas authors such as Plan S.

ANSTO authors are encouraged to use a CC-BY licence when publishing open access. Statistics have been returned to the database and are now visible to users to show item usage and where this usage is coming from.

Adsorption removal of NO2 under low‐remperature and low‐concentration conditions: a review of adsorbents and adsorption mechanisms
(Wiley, 2024-12-10) Wang, YY; Wang, TQ; Gu, QF; Shang, J
The efficient mitigation of harmful nitrogen oxides (NOx) under ambient conditions remains a challenging task. Selective adsorption offers a viable solution for the capture of low‐concentration NOx from the polluted stream at low temperatures. This review summarizes recent progress in the development of NO2 adsorbents, delves into the understanding of adsorption mechanisms, and discusses the criteria for evaluating their performance. First, the present NO2 adsorbents are categorized according to their distinct characteristics. This review then provides insights into the mechanisms of adsorption, highlighting the interaction between active sites and NO2, drawing from both experimental and theoretical research. The performance of these adsorbents is also assessed, focusing on their capacity, reusability, stability and selectivity. Finally, perspectives are proposed to address the significant challenges and explore potential advancements for NO2 adsorbents, aiming to enhance their suitability for diverse practical application scenarios. © 2025 Advanced journals portfolio

Linearly interlinked Fe‐Nx‐Fe single atoms catalyze high‐rate sodium‐sulfur batteries
(Wiley, 2024-02-08) Ruan, JF; Lei, YJ; Fan, YM; Borras, MC; Luo, ZX; Yan, ZC; Johannessen, B; Gu, QF; Konstantinov, K; Pang, WK; Sun, WP; Wang, JZ; Liu, HK; Lai, WH; Wang, YX; Dou, SX
Linearly interlinked single atoms offer unprecedented physiochemical properties, but their synthesis for practical applications still poses significant challenges. Herein, linearly interlinked iron single‐atom catalysts that are loaded onto interconnected carbon channels as cathodic sulfur hosts for room‐temperature sodium‐sulfur batteries are presented. The interlinked iron single‐atom exhibits unique metallic iron bonds that facilitate the transfer of electrons to the sulfur cathode, thereby accelerating the reaction kinetics. Additionally, the columnated and interlinked carbon channels ensure rapid Na+ diffusion kinetics to support high‐rate battery reactions. By combining the iron atomic chains and the topological carbon channels, the resulting sulfur cathodes demonstrate effective high‐rate conversion performance while maintaining excellent stability. Remarkably, even after 5000 cycles at a current density of 10 A g−1, the Na‐S battery retains a capacity of 325 mAh g−1. This work can open a new avenue in the design of catalysts and carbon ionic channels, paving the way to achieve sustainable and high‐performance energy devices. ©2024 The Authors.

Elucidating sodium ion storage mechanisms in hard carbon anodes at the electronic level
(Wiley, 2025-02-17) Xia, QB; Ko, CL; Cooper, ER; Gu, QF; Knibbe, R; Harmer, JR
Sodium‐ion batteries (SIBs) are a promising technology for advanced energy storage systems. Hard carbon (HC) is a commonly used SIB anode material; however, the Na ion storage mechanism in HC remains poorly understood and highly debated. Here, the paramagnetic species in HC during Na ion storage are systematically studied to elucidate the underlying mechanism at an electronic level using high‐resolution electron paramagnetic resonance (EPR) spectroscopy, complemented by in situ Raman spectroscopy, in situ synchrotron X‐ray diffraction, and density functional theory calculations. This investigation identifies and characterizes the coexistence of two distinct intercalation processes in HC: Na ion intercalation and Na+‐solvent co‐intercalation, which are active across both the sloping and plateau voltage regions. Additionally, in the sloping region, Na ions are also stored at in‐plane Stone‐Wales defect sites, which transition into a quasi‐metallic state and subsequently to metallic Na as Na ion intercalation progresses. This transformation is driven by charge redistribution within the graphene layers. These insights establish a direct paramagnetic‐electronic structure‐electrochemical property relationship in HC, providing new insights into the Na ion storage mechanism. Furthermore, this study highlights the unique capability of EPR spectroscopy in elucidating the charge storage mechanism in electrode materials. © 2025 The Author(s).

Phase segregation-dictated superior Fe-rich ferrite composite for intensified methane dry reforming with CO2 splitting
(Elsevier, 2025-03-01) Appiagyei, AB; Yang, S; Gu, JX; Chaffee, A; Liu, JZ; Gu, QF; Zhang, L
Earth-abundant iron oxide serves as a promising oxygen carrier for the chemical looping dry reforming of methane, addressing the emission of both CH4 and CO2. However, its development faces a challenge with a trade-off between high activity and stability. We successfully resolved this issue by advancing an Fe-rich (61 wt% Fe) oxygen carrier derived from a global waste, fly ash. This oxygen carrier incorporates six cations (Fe, Mg, Al, Ca, Ti and Mn) in a composite consisting of distorted spinel ferrites (MgFeAlO4 and Fe3O4) and discrete oxides (MgO and Fe2O3), recording a superior oxygen transfer capacity of ∼ 19.8 mmol/gOC during the 900 °C CH4/CO2 cycles. This is attributed to a promoted deep reduction of Fe3+, a high phase segregation of the structure due to oxygen migration, and a strong metal-support interaction between inert MgO and the deeply reduced metallic Fe0. Additionally, the oxygen carrier is capable of catalysing both CH4 reforming and cracking reactions, yielding a high H2/CO molar ratio of 5.3 and a large H2 production (∼70.6 mmol/gOC) in the CH4 reduction stage. In the subsequent CO2 oxidation stage, the lattice oxygen is fully restored, and the Boudouard reaction is also catalysed by the trace cations (Ca, Ti and Mn) to eliminate the coke deposit effectively, which resulted in a total CO production of ∼ 82 mmol/gOC. Meanwhile, the segregated phases are re-integrated together, enabling a successful reversion of the structure for the oxygen carrier and its constantly high and stable activity over cyclic use. © 2025 The Author(s).

Revisit the molecular sieving mechanism in LTA zeolites: does size really matter?
(Springer Nature, 2025-03-13) Sun, MZ; Hanif, A; Wang, TQ; Tao, ZY; Chen, DS; Li, G; Liu, Z; Gu, QF; Webley, PA; Shang, J
“Molecular sieving”-based separation of similar-sized gases (e.g., CO2, N2, and CH4) is both desirable and challenging due to the difficulty of obtaining adsorbents with pore sizes that permit exclusive admission. The “molecular trapdoor effect” offers a promising solution, focusing on the difference in gases’ ability to dynamically open a “door” via interaction with the “door-keeper” in adsorbents, rather than relying on size-sieving. In this study, we studied Na and K-exchanged zeolites with Si/Al ratios ranging from 1 to 2.2 and demonstrate that potassium form zeolite LTA with a Si/Al ratio of 2.2 (referred to as r2KLTA) exhibits the molecular trapdoor mechanism, as evidenced by CO2/N2 separation, gas adsorption, and in situ powder X-ray diffraction experiments. The K+ ion, acting as the door-keeper, is situated at the eight-membered ring (8MR) pore aperture of LTA, enabling the exclusive separation. Notably, this separation mechanism diverges from the traditional static sieving model and suggests that gas molecule admission is regulated by dynamic door-opening. In contrast to previous reports showing negligible CO2 adsorption in r1KLTA (3 A zeolite), our findings reveal a significant CO2 uptake, which points to the trapdoor mechanism as the key factor. This study offers new insights into the classical zeolite molecular sieve (3 A) for gas separation, where gas selectivity is governed by dynamic door-opening rather than static interactions. The demonstrated molecular trapdoor effect in r2LTA zeolites opens new possibilities for designing adsorbents with high selectivity and enhanced kinetics at optimal temperatures. © 2025 Springer Nature
