NOVELTY - Preparation of three-dimensional porous carbon/composite metal oxide photocatalyst involves (s1) preparing a phenolic resin/graphene oxide porous organic template by sol gel method, (s2) preparing phenolic resin/composite metal salt precursor by dripping method based on phenolic resin/graphene oxide porous organic template, (s3) dripping alkali solution in phenolic resin/composite metal salt precursor, reacting to generate hydroxide, and placing in drying oven for full drying, and (s4) using heat-treatment method based on hydroxide. USE - Preparation of three-dimensional porous carbon/composite metal oxide photocatalyst. ADVANTAGE - The method overcomes the limitations of sol gel method on gel condition of the precursor liquid system, the limitation of high-pressure chamber in the hydrothermal process, and difficulties of particle agglomeration in drying and heat treatment process of the liquid phase method, is simple, inexpensive, and requires low equipment, which is suitable for mass production.
