The present invention relates to a novel process for the preparation of a nitrogen containing biopolymer-based catalyst and to the novel nitrogen containing biopolymer-based catalysts obtainable by this process. In particular, the invention relates to a novel nitrogen containing biopolymer-based catalyst comprising metal particles and at least one nitrogen containing carbon layer. The invention also relates to the use of a nitrogen containing biopolymer-based catalyst in a hydrogenation process, preferably in a process for hydrogenation of nitroarenes, nitriles or imines; in a reductive dehalogenation process of CX bonds, wherein X is Cl, Br or I, preferably in a process for dehalogenation of organohalides or in a process for deuterium labelling of arenes via dehalogenation of organohalides; or in an oxidation process. Further, the invention relates to a metal complex with the nitrogen containing biopolymer, wherein the metal is a transition metal selected from the group consisting of manganese, ruthenium, cobalt, rhodium, nickel, palladium and platinum, and wherein the nitrogen containing biopolymer is selected from chitosan, chitin and a polyamino acid.
