The perfluorosulfonic acid(PFSA) membrane doped with two-dimensional conductive filler Ti_(3)C_(2)T_(x) is a fuel cell proton exchange membrane with high application potential. Experimental studies showed that the proton conductivity of Nafion/Ti_(3)C_(2)T_(x) composite membrane is improved significantly compared with that in pure Nafion. However, the microscopic mechanism of doping on the enhancement of membrane performance is remain unclear now. In this work, molecular dynamics simulation was used to investigate the microscopic morphology and proton transport behaviors of Nafion/Ti_(3)C_(2)T_(x) composite membrane at the molecular level. The results shown that there were significant differences about the diffusion kinetics of water molecules and hydroxium ions in Nafion/Ti_(3)C_(2)T_(x) at low and high hydration levels in the nanoscale *** the increase of water content, Ti_(3)C_(2)T_(x) in membrane was gradually surrounded by ambient water molecules to form a hydration layer, and forming a relatively continuous proton transport channel between Nafion polymer and Ti_(3)C_(2)T_(x) monomer. The continuous proton transport channel could increase the number of binding sites of proton and thus achieving high proton conductivity and high mobility of water molecules at higher hydration level. The current work can provide a theoretical guidance for designing new type of Nafion composite membranes.

Harvesting the Vibration Energy of CdS for High-Efficient Piezo-Photocatalysis Removal of U(Ⅵ):Roles of Shape Dependent and Piezoelectric Polarization

引用

Energy & Environmental Materials 2024年第5期7卷 391-403页

作者： Zhimin Dong Donglin Gao Zifan Li Haonan Pei Lin Xu Jian Huang Xiaohong Cao Youqun Wang Ting Wang Qianglin Wei Zhibin Zhang Yunhai Liu State Key Laboratory of Nuclear resources and Environment East China University of Technology institute of Geology Chinese Academy of Geological Sciences

Piezo-photocatalysis could coalesce the advantages of mechanical vibration and solar energy perfectly to achieve high-efficiency catalytic activity. Herein,the quintessential piezoelectric material CdS nanowires with different aspect ratios are precisely constructed and applied for piezo-photocatalytic reduction of U（Ⅵ） for the first time. The ultrasonic （60 kHz, 100 W） induces piezoelectric potential to generate a 0.57 eV A-1electric field, which is added to the direction of CdS （010） as a driving force to efficiently separate photogenerated charges. The alliance between piezoelectric effect and photocatalytic activity endows CdS NW-3 with the fastest piezophotocatalytic rate under ultrasonic vibration and 5 W LED irradiation, and the relevant rate constant (0.042 min-1) is about 12 and 53.8 times than that of LED and ultrasonication. More importantly, 93.74%of U（Ⅵ） could be removed from natural uranium mine wastewater. Therefore, this piezophotocatalysis system that reduces U（Ⅵ） to easily separable （UO2）O2·2H2O（s） provides valuable input for disposal applications of radioactive wastewater and broadens the horizons of nuclear energy utilization toward the advancement of carbon neutrality.
