The utilization of CO2 electrochemistry in energy storage has been considered as a promising power source due to its high theoretical energy density, high electrochemical potential, and ability to fix CO2. However, the low efficiency and poor reversibility of Li-CO2 evolution significantly impede the applications of Li-CO2 batteries. Herein, first-principles calculations were employed to investigate the 21 M1M2N4C active sites and explore the catalytic mechanism for the Li-CO2 evolution reaction. The adsorption and activation of CO2 on the thermodynamically stable DACs show that the TM atoms in M1M2N4C center sites with decreasing d-band center appeared to increase CO2 adsorption energy. Among the active sites, the MoMoN4C shows the most robust activation interaction with CO2 due to its high d-center and strong d-p orbital coupling. The implicit solvent CEP simulations verify the effects of dual-atom sites on the products' activities and selectivity by searching the possible reaction pathways toward the battery-discharging processes in the ether electrolyte. The decomposition of *Li2CO3 was simulated by the NEB calculations. The results prove that the MoMoN4C active site can boost the reaction dynamics and exhibit high reversibility for the Li-CO2 battery. © 2024, The Authors. All rights reserved.

Durable ruthenium oxide catalysts for water oxidation reaction

作者： Jixiang Jiao Ding Chen Hongyu Zhao Ying Dong Shichun Mu State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology

Water electrolysis is an important way for high-purity hydrogen production. However, the oxygen evolution reaction（OER）, as a key reaction, has a high energy barrier, and the associated catalyst is prone to failure. Therefore, efficient and stable OER catalysts are urgently required. Compared with commercial iridium oxide（IrO2）, ruthenium oxide（RuO2） has a lower price and higher catalytic activity for OER due to its location at the near-top of the volcano plot, but has lower structural stability. Thus, an in-depth understanding of the failure mechanism of RuO2is conducive to the reaction pathway design and structural modulation for obtaining higher stable Ru O2catalysts. Here, we discuss recent advances in the enhancement of the stability of RuO2catalysts. First, we analyze in depth the three failure modes of RuO2, including the oxidation of Ru, the lattice oxygen evolution,and the catalyst exfoliation during the OER process. Second, to improve the durability of RuO2catalysts, five modification strategies, comprising defective engineering, strain engineering, phase engineering, interface engineering and microenvironmental engineering, are summarized, and corresponding enhancement mechanisms are also discussed. Finally, the challenges and possible solutions for further breakthroughs of RuO2catalysts are proposed, and the future research trends and prospects of RuO2catalysts are also envisioned. Undoubtedly, this work will contribute to the understanding and design of highly stable OER catalysts and beyond.

Iron-doped Nano-hydroxyapatite: Preparation and Ultraviolet Absorption Performance

引用

Wuji Cailiao Xuebao/Journal of Inorganic materials 2025年第5期40卷 457-465页

Nano-hydroxyapatite (nHAP) possesses both biocompatibility and environmental friendliness, and holds the potential to become a novel ultraviolet (UV) absorbent material following iron doping modification. This study employed co-precipitation and hydrothermal methods to prepare iron-doped nano-hydroxyapatite (Fe-nHAP). Influence of the preparation process on UV absorption performance was investigated by adjusting reaction time, temperature, and iron doping ratio. The results indicate that with the increase of temperature from 37 ℃ to 150 ℃ or the extension of reaction time from 0.5 h to 3 h, both the crystallinity and the peak of UV absorption improve. It can be inferred that there is a certain positive correlation between the UV absorption performance and crystallinity of Fe-nHAP. Additionally, the UV absorption capacity is closely correlated to the iron doping ratio. As the iron doping molar ratio increases from 0 to 10%, the UV absorption capacity is gradually enhanced, with the maximum absorption value rising from 0.03 to 1.35. This phenomenon is attributed to the reduction in optical bandgap caused by iron doping. However, a high iron doping ratio leads to excessive reduction in material crystallinity, resulting in weakened enhancement of UV absorption performance. The safety assessment indicates that Fe-nHAP with an iron doping molar ratio of 7% does not demonstrate cytotoxicity, phototoxicity and skin irritation. In summary, Fe-nHAP has a suitable UV absorption performance. With its favorable biosecurity, it is anticipated to emerge as a new type of UV absorption material. © 2025 Science Press.
