Embodiment 1～7

[0044] Add 20mL of deionized water into a 50mL beaker, heat it to 80°C with a heater with temperature control function, add 1g of dicyandiamide, stir it until it is completely dissolved, and then add a certain amount of ferric chloride hexahydrate according to the data in Table 1 , continue stirring for 1 h, and then add 0.1 g of mesoporous graphitic carbon. Heat to 120°C and continue to stir until the water evaporates completely. The above mixture was slightly ground to obtain a black powder, which was placed in a tube furnace and calcined under nitrogen atmosphere for 3 hours according to the temperature in Table 1, with a heating rate of 10°C / min.

Abstract

The invention discloses a preparation method of a fe-doped carbon nitride / mesoporous graphite carbon composite catalyst. The method comprises the steps that 1, dicyandiamide is added into hot water, ferric salt is added for a period of time after the dicyandiamide is dissolved completely, mesoporous graphite carbon is added, continuous heating is performed till water is evaporated completely, and slight grinding is performed to obtain black powder; 2, the black powder is placed into a tube furnace to be calcined under the protection of nitrogen gas, and the fe-doped carbon nitride / mesoporous graphite carbon composite catalyst is obtained. The invention further discloses the catalyst obtained through the preparation method and an application method of the catalyst. Due to mutual effects of Fe, graphite phase carbon nitride and mesoporous graphite carbon, Fe is mainly dispersed into the catalyst in an N-coordinate mode, and the quite high Fenton-like catalytic activity can be shown.

Description

technical field [0001] The invention belongs to the technical field of catalyst preparation, and in particular relates to a preparation method, product and application of an iron-doped carbon nitride / mesoporous graphite carbon composite catalyst. Background technique [0002] With the rapid development of the economy, people are increasingly strict with the discharge of sewage. However, organic pollutants in wastewater, especially some high-concentration and refractory organics, pose considerable challenges to current wastewater treatment systems. These organic wastewaters are mainly distributed in chemical industry, metallurgy, coking, light industry, medicine and other industries. They have large emissions, complex components, and are difficult to biochemically degrade. Therefore, after traditional treatment methods, the water quality often fails to meet the discharge standards. Among the new treatment technologies, the Fenton technology has the advantages of simple equip...
