摘要: 光催化技术是一种将太阳能转换为化学能的新技术,基于该技术可利用半导体光催化材料实现光催化分解水制氢、二氧化碳还原制备有机物、降解有机污染物等,是解决未来能源和环境问题的潜在途径之一。然而,作为光催化技术的核心,光催化材料面临着光吸收范围窄、光生载流子分离效率低等问题,这些问题严重制约着光催化能量转化效率及其实际应用。针对制约光催化材料活性的关键科学问题,近年来本课题组从晶体学基本原理出发,基于半导体材料结构与性能的关系,通过对半导体材料的晶体结构、电子结构、微结构参数进行设计与调控,探索制备了一系列具有宽光谱响应范围、高载流子分离效率的新型高效光催化材料,为设计制备新型高效光催化材料提供了一些新的设计思路和材料制备方法。
