Abstract: An electrode catalyst for a fuel battery includes a mesoporous material and catalyst metal particles supported at least in the mesoporous material. In the electrode catalyst for a fuel battery, before supporting the catalyst metal particles, the mesoporous material has mesopores having a mode radius of greater than or equal to 1 nm and less than or equal to 25 nm and has a value of greater than 0.90, the value being determined by dividing a specific surface area S1-25 (m2/g) of the mesopores obtained by analyzing a nitrogen adsorption-desorption isotherm according to a BJH method, the mesopores having a radius of greater than or equal to 1 nm and less than or equal to 25 nm, by a BET specific surface area (m2/g) evaluated according to a BET method.

Abstract: A photoelectrode (100) of the present invention includes a conductive layer (12) and a photocatalytic layer (13) provided on the conductive layer (12). The conductive layer (12) is made of a metal nitride. The photocatalytic layer (13) is made of at least one selected from the group consisting of a nitride semiconductor and an oxynitride semiconductor. When the photocatalytic layer (13) is made of a n-type semiconductor, the energy difference between the vacuum level and the Fermi level of the conductive layer (12) is smaller than the energy difference between the vacuum level and the Fermi level of the photocatalytic layer (13). When the photocatalytic layer (13) is made of a p-type semiconductor, the energy difference between the vacuum level and the Fermi level of the conductive layer (12) is larger than the energy difference between the vacuum level and the Fermi level of the photocatalytic layer (13).
