Abstract

The invention discloses the preparation of an ultra-thin porous nano-carbon nitride photocatalyst and its application in photocatalytic oxidation of fructose to synthesize lactic acid, which belongs to the technical field of catalysis. The preparation method of the catalyst is as follows: dispersing the nitrogen-containing compound precursor and manganese acetate hydrate in deionized water, and then calcining to obtain the Ut-OCN material with oxygen heteroatoms introduced into the structure. The application process of the catalyst in the photocatalytic oxidation of fructose to synthesize lactic acid is as follows: mix the Ut-OCN photocatalyst, fructose and alkaline solution, and react with visible light at 20-80°C for 45-180min; Determination of lactic acid content by liquid chromatography. The method for preparing the catalyst of the present invention has better universality, and the catalyst used has the advantages of high catalytic activity, good thermal stability, recyclability, etc., lactic acid is synthesized by simple and efficient catalysis, and has good application prospect.

Description

technical field

[0001] The invention relates to the preparation of an ultra-thin porous nanometer photocatalyst and its application in photocatalytic oxidation of fructose to synthesize lactic acid, belonging to the field of catalytic technology. Background technique

[0002] With the depletion of non-renewable resources such as petroleum and the increasingly prominent environmental problems, resource utilization is constantly shifting to non-fossil, clean and renewable resources. As an important renewable resource, biomass has the advantages of abundant sources, renewable and biodegradable, and has become one of the energy sources that can replace fossil fuels. Lignocellulose is the most abundant natural polymer compound, and its transformation and utilization are of great significance to solve environmental problems and promote the sustainable development of society. As an important biomass-based monosaccharide, fructose is an isomer of glucose, which can be converted int...
