Abstract

The invention discloses a TiO2@C / CdS composite material and a preparation method thereof. TiO2@C hollow spheres are prepared by a hard template process, the TiO2@C hollow spheres are compounded with CdS synthesis raw materials in different mass fractions, and the obtained compounded product is washed and dried to prepare the TiO2@C / CdS composite material. The composite and unique hollow structureof three materials is utilized to greatly improve the visible light utilization rate of the catalyst and inhibit the recombination rate of photogenerated carriers. The TiO2@C / CdS composite material prepared in the invention has excellent catalytic performances in the degradation of organic dyes as a photocatalyst.

Description

technical field

[0001] The present invention relates to a kind of TiO 2 The @C / CdS composite material and its preparation method belong to the field of micron material preparation. Background technique

[0002] With the continuous development of industrial technology, the ensuing environmental pollution problem has now seriously threatened people's lives. Photocatalytic technology has broad application prospects in dealing with environmental pollution problems, but photocatalytic technology still faces severe challenges in practical applications. The problems limit its large-scale application, so it is necessary to develop efficient and stable photocatalytic technology. TiO 2 It is the first material used to study photocatalysis, but it has many shortcomings, such as low utilization rate of sunlight, high recombination rate of photogenerated carriers, etc., through semiconductor recombination, noble metal doping, introduction of defects and heteroatoms and other technologi...
