Abstract

The invention discloses a preparation method of a carbon dot hybridization mesoporous nickel boride photocatalyst. According to the method, the carbon dot hybridization mesoporous nickel boride photocatalyst is prepared by the steps of citric acid solution preparation, nickel addition, hydrothermal reaction, pH (potential of hydrogen) value adjustment, sodium borohydride addition reaction and centrifugation. The preparation method of the carbon dot hybridization mesoporous nickel boride photocatalyst has the advantages of simple process, easiness in control, high yield and the like.

Description

technical field [0001] The invention belongs to the technical field of nanomaterials and catalysis, and in particular relates to a preparation method of a carbon-dot hybrid mesoporous nickel boride photocatalyst. Background technique [0002] Mesoporous materials refer to a class of porous materials with pore sizes ranging from 2 to 50 nm. The pores of mesoporous materials are not only conducive to increasing the reaction contact area, but also conducive to the adsorption and separation of organic molecules, so they are used as efficient "microreactors" and play an important role in catalytic reactions. A new type of hybrid material is formed after grafting or assembling nanoscale and uniform and stable functional nanoparticles in the channels of mesoporous materials. This new type of hybrid material combines the properties of mesoporous materials and nanomaterials, and has a super small size. effect, quantum size effect, etc., so that it has more excellent performance. ...
