Abstract
Disclosed is—the synthesis of novel supported metal catalytic materials for electromagnetic radiation absorption and chemical catalysis especially in the presence of plasma used in the conversion of nitrogen from air and hydrogen from water to useful products such as nitric acid, hydrogen, ammonia and fertilizers. These materials can also generate plasma when subjected to microwave irradiation thus form the basis of catalytic plasma reactors. They can be used in chemical looping reactions because plasma generation under microwave irradiation in air results in the reduction of catalyst oxides and oxidation of nitrogen.
Claims10
A process for preparing a supported micro-porous multi-metal catalyst, comprising performing microwave radiation in self-generated plasma environment to a mixture comprising a multi-metal catalyst and a silane-coated silica support to obtain the supported micro-porous multi-metal catalyst, wherein the multi-metal catalyst is prepared by combining:
- (a) at least one transition metal catalyst having two stable valence states and at least one transition metal catalyst having three stable valance states;
- (b) at least one transition metal catalyst having two or three stable valence states and at least one transition metal catalyst having a single valence state;
- or
- (c) at least one of the transition metal catalyst having two or three stable valence states and at least one non-transition metal catalyst having two stable valance states.
