Nitrogen-containing biopolymer-based catalysts, methods for their preparation and their use in hydrogenation processes, reductive dehalogenation, and oxidation

摘要

The present invention relates to a method for preparing a nitrogen-containing biopolymer-based catalyst by thermal decomposition of a metal complex with a nitrogen-containing biopolymer, and a nitrogen-containing biopolymer-based catalyst obtainable by the method. In particular, the present invention relates to a nitrogen-containing biopolymer-based catalyst comprising metal particles and at least one nitrogen-containing carbon layer. The present invention relates to a hydrogenation method, preferably a hydrogenation method of nitroallene, nitrile or imine; a reductive dehalogenation method of CX bond, wherein X is Cl, Br or I, preferably a dehalogenation method of an organic halide. Or deuterium labeling of allenes by dehalogenation of organic halides; or the use of nitrogen-containing biopolymer-based catalysts in oxidation processes. Further, the present invention provides a metal complex with a nitrogen-containing biopolymer, wherein the metal is a transition metal selected from the group consisting of manganese, ruthenium, cobalt, rhodium, nickel, palladium and platinum, preferably cobalt or nickel. And a metal complex wherein the nitrogen-containing biopolymer is selected from chitosan, chitin and polyamino acids, preferably chitosan or chitin.
