Abstract

The invention relates to a preparation method of a chemical nanomaterial catalyst, and especially relates to a preparation method of an iron and nitrogen doped carbon nanoparticle photocatalyst. The method comprises the following steps: mixing materials: weighing 1.0g of a carbon source substance and 1.0g of a substance rich in amino groups, carboxyl groups and hydroxy groups, mixing the above substances in a 250mL beaker, adding 0.1g of iron trichloride, and adding a small amount of distilled water to dissolve above substances in order to obtain a purple solution; generating iron and nitrogen doped carbon nanoparticles: placing the solution in a constant temperature drying box, and heating at 210DEG C for 2h; and naturally cooling to obtain a brown-yellow foam solid in the beaker, wherein the solid is the iron and nitrogen doped carbon nanoparticles. The iron and nitrogen doped carbon nanoparticle solid is synthesized through direct co-heating with the carbon source substance and the substance rich in amino groups, carboxyl groups and hydroxy groups as precursors and iron trichloride as an iron source, so the method has the advantages of wide material sources, few synthesis steps, fast synthesis speed, no need of large scale devices, less investment, realization of macro production, and suitableness for industrial requirements.

Description

technical field [0001] The invention relates to a method for preparing chemical and nanometer materials, in particular to a method for preparing an iron-nitrogen-doped carbon nanoparticle photocatalyst. Background technique [0002] Due to their excellent optical and electrical properties, carbon nanoscale particles have been widely used in bioimaging, in vivo labeling, solar energy, and catalysts. Because carbon nanoparticles have the nature of semiconductor materials, and have electron holes on the surface, they can generate photogenerated electrons under light irradiation, and are electron acceptors and donors, with photocatalysis. Research on carbon nanoparticles as a catalyst has been reported, most of which use carbon nanoparticles to catalyze the degradation of dye wastewater, and the efficiency is limited. In order to improve the efficiency and enrich the variety of catalysts, people combine carbon nanoparticles and metals to form metal-doped carbon nanoparticles to...
