摘要: 二氧化钛(TiO2)材料由于其低成本、天然丰度高、对环境友好、具有良好的化学稳定性和优异的光学性能受到人们越来越广泛的关注。其中,有序介孔TiO2材料因其高比表面积、大的孔体积、可调的孔结构和形态,在物理、化学、材料科学等方面得到了广泛的应用。本文,我们总结了通过合理控制钛前体水解和交联速率合成有序介孔TiO2材料的重要进展,同时讨论了其在光催化分解水产氢方面的应用,并对该领域的发展趋势和所面临的的挑战提出展望。

Abstract: Titanium dioxide (TiO2) materials have attracted much attention due to their low cost, high natural abundance, environmental friendliness, good chemical stability and excellent optical properties. Among them, ordered mesoporous TiO2 materials have been widely used in physics, chemistry, materials science due to their high surface area, large pore volume, adjustable pore structure and morphology etc. In this article, we summarize the synthesis of ordered mesoporous TiO2 by reasonably controlling the rate of hydrolysis and crosslinking of titanium precursors. Furthermore, the application of mesoporous TiO2 in the photocatalytic splitting of water to produce hydrogen is also discussed. Finally the challenges in this field are proposed.
