1.引言

当今社会，能源对社会经济的发展及人类生活水平均起到至关重要的作用。传统的一次能源，以煤、石油、天然气为代表的化石燃料日益短缺，面临枯竭。开发新型的可替代能源是实现社会可持续发展的必经之路。相比于核能、风能、水能等二次能源，氢能具有热值高(142kJ/kg)、稳定性高、使用过程清洁，无二次污染等优势。因此，针对产氢、储氢等领域的研究日益成为热点。目前已经出现的产氢技术

主要包括电化学产氢、厌氧微生物发酵产氢及光催化产氢等。相比于前两种技术，光催化产氢能够直接以水为生产原料，在催化剂作用下将光能转化为氢能。而在自然界中，太阳光被认为是一种取之不尽用之不竭的光源。因此，开展光催化产氢技术的研究具有重要的科学意义及战略意义。

2.光催化产氢的基本原理

光催化产氢技术最早由日本科学家Fujishima利用TiO 2
