摘    要:
电催化过程是时空多尺度的复杂系统,探究认识多孔电极电催化体系中不同层次和尺度下的介尺度行为,对进一步强化电催化反应以及物质扩散传递,提高效率减低能耗具有重要的意义。围绕多孔电极、电催化剂以及隔膜,对多级孔电极结构的构筑、电催化剂表界面活性位调控、介尺度结构可控制备策略和隔膜结构调控中存在的介尺度现象以及介尺度效应进行了详细的综述,发现电催化体系中各层次之间的介尺度行为可以用于优化、调控、指导多孔电极、电催化剂以及隔膜的设计与制备,为丰富和完善电化学催化体系提供了新思路和新角度。

关 键 词:介尺度  多孔电极  电化学催化  催化剂  隔膜

Abstract:
The electrocatalytic process is a complex system engineering involving multiscale scientific problems. It is of great significance to explore and understand the mesoscale behavior of porous electrode electrocatalytic systems at different levels and scales, which is of great significance to further strengthen the electrocatalytic reaction and material diffusion and transfer, improve efficiency and reduce energy consumption. This paper gives a detailed review to the construction of hierarchically porous electrodes, tuning of the active sites located at the surfaces and interfaces, design and controlled preparation of mesoscale structures, the mesoscale characteristics and effects of the membrane materials. It is interesting to find that a deep understanding of the varied-level mesoscale mechanisms may lead to optimal and tunable design and preparation of porous electrodes, electrocatalysts, and membranes, and thus supply copious novel ideas and perspectives for forming a perfect and complete theory system for electrochemical catalysis.
Keywords:mesoscale  porous electrode  electrochemical catalysis  catalysts  membrane
