新型光催化剂光解水制氢摘要随着人类社会的步步发展，能源问题越来越变得必须关注，如化石燃料等旧能源已经储量不足，且会造成一定的环境污染，对于可再生能源以及新能源的开发也就变得尤为重要。由于氢能所具有的环境友好，制造技术相对较成熟等特点，氢能已成为当下清洁新能源研究的热点。氢不是一种自然能源，它需要各种能源和材料来生产。半导体可见光催化光解水制氢是一种很重要的产氢方式。并符合环境友好，高效产氢等要求。本文致力于总结现有的光催化剂，并提出一种高效可行的半导体光催化剂。关键词：光解水制氢；光催化剂；半导体PAGE\*MERGEFORMAT新型光催化材料光解水制氢AbstractThedevelopmentofnewandrenewablesourcesofenergyisparticularlyimportantinviewofenergyshortagesandsustainableeconomicdevelopment.Withthedevelopmentofhydrogenproductionandhydrogenstoragematerialtechnology,hydrogenenergyhasbecomeahotspotofcleanenergyresearch.Hydrogenisnotanaturalenergysourceandrequiresavarietyofenergysourcesandmaterialstoproduceit.Hydrogenproductionbyphotocatalyticdecompositionofwaterisaveryimportantenvironmentallyfriendlyandcleanenergypreparationtechnology,whichmeetstherequirementsofenvironmentalfriendlyandefficienthydrogenproduction.Inthispaper,wesummarizetheexistingphotocatalystsandproposeanefficientandfeasiblesemiconductorphotocatalystKeywords：Photolysiswaterforhydrogenproduction;Photocatalyst;semiconductorPAGE\*MERGEFORMAT121新型光催化材料光解水制氢目录摘要.................................................................................................................IAbstract................................................................................................................II1绪论...................................................................................................................12光解水制氢原理及发展现状...........................................................................22.1光解水制氢原理.........................................................................................32.2半导体光催化剂及光催化机理的研究.....................................................43光催化剂种类及研究.......................................................................................73.1金属氧化物半导体光催化剂...................................................................103.2金属硫化物半导体光催化剂...................................................................113.3金属氮(氮氧)化物光催化剂....................................................................123.4石墨碳氮化物光催化剂...........................................................................123.5异质结构半导体光催化剂.......................................................................134高效催化剂TaON及原理.............................................................................134.1TaON的制备............................................................................................134.2在可见光下TaON光催化制氢和影响因素研究...................................144.3提高光催化活性理论分析.......................................................................154.4TaON光解水制氢性能的研究................................................................174.5TaON光催化反应机理的探讨................................................................214.6小结..........................................................................................................22致谢.............................................................
