Abstract

The invention discloses a Pt/g-C3N4/AC functional carbon adsorbing material and a preparation method and application thereof. The thermocatalytic function of precious metal Pt, the photocatalytic function of polymer g-C3N4 and the strong adsorption function of activated carbon are organically combined to prepare an efficient carbon adsorbing material Pt/g-C3N4/AC with adsorption-thermocatalytic-photocatalytic function, the carbon adsorbing material Pt/g-C3N4/AC has good effect when being used for purifying pollutant. The application area of g-C3N4 is expanded, and the quality and the application range of the activated carbon are improved. The existence of the activated carbon improves the dispersity of g-C3N4 and improves the catalytic activity of the g-C3N4; the existence of the g-C3N4 improves the adsorption performance of the activated carbon; the existence of the precious metal Pt promotes the thermocatalysis property. The Pt/g-C3N4/AC has good effect while adsorbing and degrading volatile pollution gas, the gas humidity influence is small, and the in situ photocatalytic regeneration is realized.

Description

technical field [0001] The invention belongs to the field of functional carbon materials, in particular to an adsorption-thermocatalysis-photocatalysis functional carbon adsorption material Pt / g-C 3 N 4 / AC and its preparation method and application. Background technique [0002] Activated carbon is widely used in food industry, chemical industry, environmental protection and other fields because of its developed pore structure, strong adsorption capacity, rich surface functional groups, high mechanical strength, and chemical inertness. However, due to the lack of activated carbon varieties, low technical content, and lack of functional high-quality special activated carbon, my country's activated carbon industry is restricted from moving towards a higher level of application. Modification of activated carbon to develop functional activated carbon that can efficiently and deeply purify pollutants is an effective way to reduce the cost of activated carbon, expand its scope ...
