METHOD FOR SYNTHESIZING COMPOSITE PHOTOCATALYTIC MATERIAL HAVING PHOTOTHERMAL SYNERGISTIC EFFECT

摘要

A method for preparing a composite photocatalytic material having photothermal synergistic catalytic effects, comprising the following steps: (1) synthesis of a titanium silver peroxide ammonia complex precursor, (2) preparation of an ordered mesoporous microsphere complex, and (3) preparation of an ordered mesoporous metal/titanium dioxide composite. According to the preparation method, the molar ratio of the final product is controlled on molecular scale by means of synthesizing a titanium silver peroxide ammonia complex precursor, which is beneficial for carrier migration and improves catalytic activity. In situ synthesis of a nanostructure is achieved by means of the templating effect of a surfactant. The preparation method has a simple process, high operability and relatively low cost, is suitable for mass preparation, and has the potential of industrial production and broad application prospect.
