Abstract
According to one embodiment, there is provided a catalyst including a first structure including a metal oxide substrate having a pore, and a fine particle including Cu as a main component supported on an inner surface of the substrate facing the pore, and a second structure formed on the outer surface of the first structure and including Cu as a main component. The second structure is formed into a needle with a tip thereof oriented outward from the first structure.
