Abstract

The invention discloses a preparation method of a porous Ti3C2 / g-C3N4 composite film material. The preparation method comprises following steps: Ti3C2 powder and g-C3N4 powder are prepared firstly, then the Ti3C2 powder and the g-C3N4 powder are mixed in a certain mass ratio and dispersed in a solution mixed by 100 ml of deionized water and isopropyl-ketone, an obtained mixed suspension is subjected to ultrasonic processing in nitrogen atmosphere at 45 DEG C for 6-10 h and then subjected to centrifugal treatment at the rotational speed of 3,000 r / min, unstripped aggregate is removed, a mixed solution with homogeneously dispersed Ti3C2 and g-C3N4 is reserved and filtered by a mixed cellulose ester filter membrane with the aperture of 0.05 mu m, the filter membrane is dried in vacuum at the room temperature for 20-30 h, substances on the mixed cellulose ester filter membrane are removed, and the Ti3C2 / g-C3N4 composite film material is obtained. Compared with the prior art, the prepared Ti3C2 / g-C3N4 composite film material has the advantages of flexibility, porosity and the like and can be applied to chemical synthesis of a catalyst, a hydrogen storage material and the like. The preparation method has the characteristics of simple operation, little pollution, mild and easily controlled conditions and easiness in implementation of industrial production.

Description

technical field [0001] The present invention relates to the preparation method of nanometer material, especially a kind of porous Ti 3 C 2 / g -C 3 N 4 Preparation method of composite thin film material. Background technique [0002] Energy and environmental issues are two severe challenges faced by mankind in the 21st century, and the development of clean energy has become the focus of attention. Electrocatalytic water splitting for hydrogen and oxygen production has the advantages of no pollution to the environment and easy industrial implementation, and has become the focus of research. Among them, the development of electrocatalysts for electrocatalytic hydrogen production and electrocatalytic oxygen production reactions is the key point. At present, the electrocatalysts used for this type of reaction are mostly noble metals (IrO 2 , RuO 2 ), but the high price and small natural storage of precious metals limit their large-scale application. Therefore, scientific ...
