A preparation method of carboxy-modified polyaniline/silver/silver phosphate composite material, the method first prepares N-substituted carboxypolyaniline, and introduces silver source and surface activity in the in-situ polymerization system containing N-substituted carboxypolyaniline agent, reacting to form a silver-containing composite material precursor; finally introducing a phosphorus source, using the nucleation mechanism between silver and phosphorus, and due to the N-substituted carboxypolyaniline reducing part of the silver ions to silver simple substance, and finally forming N-substituted carboxypolyaniline Aniline/silver/silver phosphate optoelectronic materials. In the modified polyaniline/silver/silver phosphate composite material prepared by the present invention, because N PANI serves as the carrier matrix of silver/silver phosphate ions, it can not only effectively prevent particle agglomeration and improve catalytic performance, but also because the polyaniline void The role of hole acceptors accelerates the separation of photogenerated electrons and holes, reduces the photocorrosion of silver phosphate, thereby improving the stability of the catalyst; ensuring the catalytic efficiency and cycle life of the composite catalytic material. |
