Synthesis and Modification of Ti-based Photocatalyst Materials and Study on the Photocatalytic Performance for Water Splitting into Hydrogen

Abstract

能源是为人类提供能量的物质或物质运动,是人类活动的基础及人类社会发展的物质前提。与传统化石能源(如煤、石油)燃烧后造成环境污染相比,氢能是一种清洁能源,氢气可以从水中获得,完全燃烧后的产物是水,不会对环境造成任何污染,是世界上最干净的能源。半导体光催化是目前最理想的光解水制氢途径,而开发高效的光催化材料是半导体光催化的关键。传统TiO2光催化剂和钙钛矿型光催化剂是目前的研究热点。 本文以钙钛矿型光催化剂Sr3Ti2O7和传统光催化剂TiO2作为研究对象。具体内容如下: (1)使用聚合合成法(PolymerizedComplexMethod,PCM)制备组分化学计量比可控的多金属氧化物Sr3...Energy sources are materials or movements providing energy for human. They are the foundation for human activity and development of human society. Compared with traditional fossil fuels, such as coal and oil, bring destruction on the environment; Hydrogen is an alternative energy source with high efficiency and pollution free. Hydrogen can be produced from clean and renewable energy sources, and t...学位:理学硕士院系专业:化学化工学院化学系_物理化学(含化学物理)学号:20042507
