【摘要】：單質鉍作為近年來報道的新型光催化材料受到了研究者的廣泛關注,本文主要介紹了鉍單質的光敏化、半導體光催化及等離子體共振光催化機理。闡述了以沉淀法、溶劑熱法、電化學法為代表的鉍單質光催化材料的主要制備方法,并探討了制備方法中表面活性劑、反應溫度以及pH對合成鉍單質的影響。歸納了鉍單質尺寸和形貌對其吸光性能的影響。在此基礎上進一步綜述了以鉍-二氧化鈦、鉍-鉍系氧化物、鉍-氧化鋅、鉍-氮化碳(C_3N_4)為主要代表的鉍-半導體復合光催化材料,并歸納了其光催化增強機理,最后闡述了鉍單質及其復合光催化材料的發(fā)展趨勢。
[Abstract]:Bismuth as a new type of photocatalytic material reported in recent years has received extensive attention. In this paper, the mechanisms of Guang Min, semiconductor photocatalysis and plasmon resonance photocatalysis of bismuth are introduced. The main preparation methods of bismuth photocatalytic materials represented by precipitation method, solvothermal method and electrochemical method were described. The effects of surfactant, reaction temperature and pH on the synthesis of bismuth were discussed. The effects of the size and morphology of bismuth on the absorptivity of bismuth were summarized. On this basis, the bismuth-semiconductor composite photocatalytic materials with bismuth-titanium dioxide, bismuth-bismuth oxides, bismuth-zinc oxide and bismuth-carbon nitride (C_3N_4) as the main representatives are reviewed, and the mechanism of their photocatalytic enhancement is also summarized. In the end, the development trend of bismuth and its composite photocatalytic materials is reviewed.
