【摘要】：貴金屬與半導(dǎo)體復(fù)合形成的催化劑具備肖特基結(jié)結(jié)構(gòu),該結(jié)構(gòu)具有整流特性和較低的界面電壓,可以調(diào)控光生電子的產(chǎn)生和流向,使電子和空穴更有效地分離,提升光催化性能。綜述了近年來肖特基半導(dǎo)體光催化劑的研究進(jìn)展,分析了晶面沉積、形貌結(jié)構(gòu)、表面等離子體效應(yīng)及共摻雜等因素對(duì)該類催化劑性能的影響,從降解污染物、制氫、二氧化碳還原等方面闡述了這類催化劑在環(huán)境控制領(lǐng)域的實(shí)際應(yīng)用,并提出了勢壘高度、產(chǎn)物控制及催化劑循環(huán)利用等潛在的研究方向。肖特基型光催化劑獨(dú)特的性質(zhì)將使其成為新的研究熱點(diǎn),得到更深入的研究和應(yīng)用。
[Abstract]:The catalyst composed of noble metals and semiconductors has Schottky junction structure, which has the characteristics of rectifying and low interface voltage, which can control the generation and flow of photogenerated electrons, and make the electrons and holes separated more effectively. The recent advances in Schottky semiconductor photocatalysts were reviewed. The effects of crystal surface deposition, morphology, surface plasma effect and co-doping on the catalytic properties of these catalysts were analyzed. The practical application of this kind of catalyst in the field of environmental control is described in the aspects of hydrogen production and carbon dioxide reduction, and the barrier height is proposed. The unique properties of Schottky photocatalyst will make it a new research hotspot and be further studied and applied.
