【Abstract】 Porous g-C₃N₄ photocatalyst has high specific surface area and porous structure,provides transport channels for photo-generated carriers and reactants,and a large number of active sites for oxidationreduction reaction,which can better solve the problems of small specific surface area,fast recombination of photo-generated carriers and low utilization efficiency of visible light in bulk g-C₃N₄.In this paper,the structural characteristics of bulk g-C₃N₄ improved by hard template method and soft template method,and the main research progress of porous g-C₃N₄ in the field of photocatalysis application are reviewed.Finally,the advantages and disadvantages of the two preparation methods,as well as the current key problems and future prospects are also summarized.更多还原
