[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.
