氮化碳光催化分解水研究进展

光能取之不尽用之不竭，利用光催化技术分解水解制氢被认为是解决能源与环境问题的有效手段之一。2009年，氮化碳聚合物半导体实现了光催化产氧与产氢水分解半反应，打破了人们对有机聚合物半导体不宜作为光催化材料的传统认识。氮化碳材料由碳、氮两种元素构成，廉价易得，且光化学性质稳定。近年来，以氮化碳为代表的不含金属组分的光催化材料逐渐成为国际光催化研究的热点之一。本文将从氮化碳材料的光催化分解水的构-效关系出发，围绕共聚合氮化碳、结晶相氮化碳和氮化碳光电极，讨论氮化碳材料在光催化分解水的研究现状与发展趋势。

The progresses of carbon nitride polymers for water splitting

Solar energy is ultimately available on Earth, and therefore developing photocatalysis for hydrogen evolution by water splitting becomes potential technology to address energy and environmental issues. In 2009, the polymeric carbon nitrides (PCNs) have been realized as a photocatalyst for hydrogen evolution and oxygen evolution, and this discovery breaks the general concept of the polymeric photocatalyst. PCN is expensive as it only consists of carbon and nitrogen elements, and meanwhile, it has presented excellent physiochemical stability. In recent year, the PCN has received increasing attention. In the review, we will focus the relationship between the PCN structure and its performance for water splitting. The progresses of PCN for water splitting will be discussion including the fields of copolymerization, crystallinity, and photoelectrochemistry, and therefore providing the clue for future developments.
