Catalyst, catalyst manufacturing method, catalyst-supported carrier, decomposition method, hydrogen manufacturing method, and carrier

摘要

To provide a catalyst capable of reducing a chemical species absorbed on a catalyst surface by light radiation and causing a reaction for selectively obtaining a desired product material without applying large heat energy, and also a method of producing the catalyst, a catalyst carrying carrier, a decomposition method, a hydrogen production method and a carrier.SOLUTION: There is provided a catalyst for reducing by light radiation a chemical species absorbed on a surface thereof originating from a processed product to obtain a product material. The catalyst is formed by doping of a second metal atom to a first material containing a first metal atom. With respect to a non-level band A of the first material containing the first metal atom, at least some of a non-level band B derived from the second metal atom and a non-level band C of the chemical species overlap.SELECTED DRAWING: Figure 2
