Abstract

The invention relates to a catalytic hydrodechlorination Pd-M/NOMC catalyst and a preparing method and application thereof. According to the catalyst, with synthetic-nitrogen-doped mesoporous carbon being a carrier, the active component is Pd-M. A one-step synthesis method is adopted to prepare a nitrogen-doped mesoporous carbon catalyst, an impregnation method can be adopted to synthesize the Pd-M/NOMC catalyst, and hydrogen, formic acid-sodium formate, methyl alcohol and the like are adopted as hydrogen sources for hydrodechlorination of chlorophenol. Nitrogen atoms are doped on a mesoporouscarbon material, the reactive site of catalysis is increased, and the activity of the catalyst is improved. The one-step method for synthesis is adopted, the nitrogen sources can be controlled from the source, the content of added nitrogen is easier to control, and the formed mesoporous structure is not easily damaged; by introducing nitrogen, the lowest binding energy position of palladium is migrated, electrons in nitrogen are migrated to the surface of palladium atoms, which improves the stability between palladium and the material.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and relates to a method for preparing a catalytic hydrogenation dechlorination Pd-M / NOMC catalyst, in particular to a method for preparing a loaded synthetic nitrogen-doped mesoporous carbon with dual functions of adsorption and catalysis. its application. Background technique [0002] Chlorinated phenolic compounds are very commonly used chemical raw materials and organic solvents in chemical and pharmaceutical industries. It is also widely used in pesticides and dyes. However, this kind of compound is a kind of organic compound that is difficult to degrade in the environment, pollutes the ecological environment, and is also considered to have carcinogenic, teratogenic, and mutagenic effects, and has a great impact on daily human health. Since the organic matter contains chlorine, which has a great impact on environmental pollution, if the chlorine in the compound is removed, its...
