光催化中二氧化硅基纳米结构的研究进展(英文)
发布时间:2024-05-19 19:09
由于太阳能转化效率对资源开发和环境净化应用的重要影响,发展高效光催化剂成为一个研究热点.光催化性能主要取决于材料的光吸收、电荷产生与分离、表面性质以及结构稳定性等特性.多孔二氧化硅因具有高比表面积、孔隙可调和表面易修饰等独特优势,而发展为一个用于构建结构明晰的纳米结构(如核-壳、蛋黄-壳和其他特殊结构)的重要平台,以有效改善上述决定光催化性能的一种或多种特性.通常,中空的结构有利于光散射和比表面积的增加,而二氧化硅作为包覆或粘结材料可对光催化剂表面改性以增强其对反应物的表面吸附和物理化学稳定性.本文综述了结构明晰二氧化硅基纳米结构的设计、合成、形成机理以及对光催化性能调控等方面的最新研究进展.
