Each conductive projection of the array of conductive projections has a semiconductor composition configured for charge carrier generation in response to solar radiation. Each conductive projection of the array of conductive projections is decorated with a co-catalyst arrangement. The co-catalyst arrangement includes gold and an oxide material.

A high entropy alloy catalyst and a method of producing hydrogen via catalytic methane pyrolysis are disclosed. The catalyst comprises a core-shell structure, where the core is an internal catalyst support, and the shell comprises a high entropy alloy encapsulating the core. The method includes introducing a high entropy alloy catalyst into a reactor. The method further includes introducing natural gas into the reaction to form a reaction mixture, operating the reactor comprising the reaction mixture, thereby forming hydrogen gas and solid carbon, and separating the hydrogen gas from the solid carbon.

Disclosed isthe 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.
