METHOD AND SYSTEM FOR ENHANCING CATALYTIC AND PHOTOCATALYTIC PROCESSES

摘要

A system for solar energy conversion includes a photoelectric cell. The photoelectric cell includes a cathode and an anode comprising a nanostructure array. The nanostructure array includes a semiconductor photocatalyst; and a plasmon resonant metal nanostructure film arranged on the semiconductor photocatalyst. The system is used in a method to produce methane by placing a photocatalytic cell in an environment containing CO2; and exposing the photocatalytic cell to visible light thereby allowing the CO2 to be converted to methane.
