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.
