Abstract

The invention discloses an ordered mesoporous carbon material loaded platinum catalyst and application of the ordered mesoporous carbon material loaded platinum catalyst to catalytic hydrogenation of an aromatic nitro compound. The catalyst has large specific surface area, large pore volume, small platinum particles and high dispersion degree, and facilitates dispersion of a reaction substrate and a product; a catalyst support has high electronic density and can facilitate the active center of the catalyst to activate the reaction substrate, the ordered mesoporous carbon material loaded platinum catalyst has the catalytic performance remarkably improved in comparison with those of platinum catalysts loaded with other carbon materials, is superior to the commercial Pt / C catalyst under an optimized experiment condition, and can be recycled.

Description

technical field

[0001] The invention relates to the application field of chemical catalytic materials, in particular to an ordered mesoporous carbon material supported platinum catalyst and its application in catalytic hydrogenation of nitro compounds. Background technique

[0002] Aniline is an important amine substance, a wide range of fine chemicals and organic intermediates, mainly used in the manufacture of drugs, dyes, resins, etc. The industrial preparation of aniline mainly includes nitrobenzene reduction method and phenol aminolysis method. Due to the relatively high cost of the phenol aminolysis method, the industrial application prospect is limited, and the nitrobenzene reduction method has become the main demand of modern industry. The main methods are iron powder reduction method and catalytic hydrogenation method, and because the iron powder reduction method will produce a large amount of organic wastewater and solid waste, which will seriously pollute the env...
