Confinement of ionomer for electrocatalytic CO2 reduction reaction via efficient mass transfer pathways

National Science Review 2024年第2期11卷 168-176页

作者： Xiaowei Du Peng Zhang gong Zhang Hui Gao Lili Zhang Mengmeng Zhang Tuo Wang Jinlong gong School of Chemical Engineering and Technology Key Laboratory for Green Chemical Technology of the Ministry of Education Tianjin University Collaborative Innovation Center of Chemical Science and Engineering(Tianjin) National Industry-Education Platform of Energy Storage Tianjin University Joint School of the National University of Singapore and Tianjin University International Campus of Tianjin University Haihe Laboratory of Sustainable Chemical Transformations

Gas diffusion electrodes（GDEs） mediate the transport of reactants, products and electrons for the electrocatalytic CO2reduction reaction（CO2RR） in membrane electrode assemblies. The random distribution of ionomer, added by the traditional physical mixing method, in the catalyst layer of GDEs affects the transport of ions and CO2. Such a phenomenon results in elevated cell voltage and decaying selectivity at high current densities. This paper describes a pre-confinement method to construct GDEs with homogeneously distributed ionomer, which enhances mass transfer locally at the active centers. The optimized GDE exhibited comparatively low cell voltages and high CO Faradaic efficiencies（FE > 90%） at a wide range of current densities. It can also operate stably for over 220 h with the cell voltage staying almost unchanged. This good performance can be preserved even with diluted CO2feeds, which is essential for pursuing a high single-pass conversion rate. This study provides a new approach to building efficient mass transfer pathways for ions and reactants in GDEs to promote the electrocatalytic CO2RR for practical applications.

Spontaneous grain refinement effect of rare earth zinc alloy anodes enables stable zinc batteries

National Science Review 2024年第7期11卷 252-262页

作者： Manjing chen Yuxiang gong Yunxiang Zhao Yexin Song Yan Tang Zhiyuan Zeng Shuquan Liang Peng Zhou Bingan Lu Xiaotan Zhang Jiang Zhou School of Materials Science&Engineering Hunan Provincial Key Laboratory of Electronic Packaging and Advanced Functional MaterialsCentral South University Institute of Materials Research Tsinghua Shenzhen International Graduate School Tsinghua University Department of Materials Science and Engineering City University of Hong Kong Hunan Provincial Key Defense Laboratory of High Temperature Wear-Resisting Materials and Preparation Technology Hunan University of Science and Technology School of Physics and Electronics Hunan University School of Chemistry and Materials Science University of Science and Technology of China Suzhou Institute for Advanced Research University of Science and Technology of China

Irreversible interfacial reactions at the anodes pose a significant challenge to the long-term stability and lifespan of zinc（Zn） metal batteries, impeding their practical application as energy storage devices. The plating and stripping behavior of Zn ions on polycrystalline surfaces is inherently influenced by the microscopic structure of Zn anodes, a comprehensive understanding of which is crucial but often overlooked. Herein, commercial Zn foils were remodeled through the incorporation of cerium（Ce）elements via the ‘pinning effect’ during the electrodeposition process. By leveraging the electron-donating effect of Ce atoms segregated at grain boundaries（GBs）, the electronic configuration of Zn is restructured to increase active sites for Zn nucleation. This facilitates continuous nucleation throughout the growth stage,leading to a high-rate instantaneous-progressive composite nucleation model that achieves a spatially uniform distribution of Zn nuclei and induces spontaneous grain refinement. Moreover, the incorporation of Ce elements elevates the site energy of GBs, mitigating detrimental parasitic reactions by enhancing the GB stability. Consequently, the remodeled ZnCe electrode exhibits highly reversible Zn plating/stripping with an accumulated capacity of up to 4.0 Ah cm-2in a Zn symmetric cell over 4000 h without short-circuit behavior. Notably, a ～0.4 Ah Zn||NH4V4O10pouch cell runs over 110 cycles with 83% capacity retention with the high-areal-loading cathode(≈20 mg cm-2). This refining-grains strategy offers new insights into designing dendrite-free metal anodes in rechargeable batteries.
