基于硅的电极在模仿自然光合作用并且直接把太阳能变换成化学能的人工的光合的系统吸引了大注意。尽管有重要努力迄今为止,硅 photoelectrodes 的催化稳定性被他们的差的电气化学的稳定性限制。钝化或保护的层的形成提供可行策略改进硅 photoelectrodes 的 photocatalytic 稳定性。包括金属,金属氧化物,金属 silicides 和聚合物的许多候选人为硅 photoelectrodes 作为保护层被探索了。现在的评论与在硅 photoanodes 和他们的 photocatalytic 活动和稳定性的结构的建筑学之间的关系的一个焦点为水氧化给保护的硅 photoanodes 的简明概述。
Silicon-based electrodes have attracted great attention in the artificial photosynthetic systems that mimic natural photosynthesis and directly convert the solar energy into chemical energy. Despite significant efforts to date, catalytic stability of the silicon photoelectrodes is limited by their poor electrochemical stability. The formation of passivation or protective layers provides a feasible strategy to improve the photocatalytic stability of silicon photoelectrodes. Many candidates including metals, metal oxi- des, metal silicides and polymers have been explored as the protection layers for silicon photoelectrodes. The present review gives a concise overview of the protected silicon photoanodes for water oxidation with a focus on the relationship between the structural architecture of silicon photoanodes and their photocatalytic activity and stability.
