质子交换膜水电解(PEMWE)制氢技术以其独特的优势被视为未来全球能源与环境协调发展的优先选择.析氧电催化剂是PEMWE制氢技术发展的关键瓶颈之一,主要原因在于其表面的析氧反应(OER)可逆性差、反应动力学过程缓慢.为了提高析氧过程反应动力学,需要研制高效的电催化剂.本文从材料组分与结构的角度出发,采用具有质子传导特性的复合载体,探索微结构可控复合载体材料的合成技术,开发出一系列的高效氧电极复合载体材料以及载体催化剂.实现载体材料高质子、电子导电性及微结构的可控优化,对于PEMWE的理论研究和应用都具有重要意义.
With its unique advantages, proton exchange membrane water electrolysis (PEMWE) hydrogen production technology is regarded as the priority of coordinated development of global energy and environment in the future.Oxygen electrocatalyst is one of the key bottlenecks in the development of PEMWE hydrogen production technology, mainly because of its The surface oxygen evolution reaction (OER) reversibility is poor, the reaction kinetics process is slow.In order to improve the reaction kinetics of oxygen evolution process, the need for the development of efficient electrocatalysts.In this paper, from the material composition and structure point of view, with proton conductivity Composite carrier to explore the synthesis of microstructure controllable composite carrier material technology to develop a series of high efficiency oxygen electrode composite carrier material and carrier catalyst to achieve carrier material high proton, electronic conductivity and microstructure controllable optimization for PEMWE Theoretical research and application are of great significance.
