Abstract
A photochemical electrode includes: an electrically-conductive layer; and a photo-excited material layer including a photo-excited material provided over the electrically-conductive layer, wherein in a surface of the photo-excited material layer, a lattice plane having highest atomic density in a crystal structure of the photo-excited material is oriented in a surface direction of the surface of the photo-excited material layer.
Claims3
A method for generating a photochemical electrode, the method comprising:
- preparing an electrically-conductive layer that contains a metal or a metal oxide;
- spraying, by an aerosol-type nanoparticle deposition (NPD) method, a photo-excited material including a wurtzite crystal structure onto the electrically-conductive layer in such a manner that raw material particles of the photo-excited material are crushed in a nozzle and a lattice plane (0001) having the highest atomic density is cleaved to form a photo-excited material layer having a first surface which faces the electrically-conductive layer and a second surface opposite to the first surface;
- and
- annealing the electrically-conductive layer and the photo-excited material layer in a gas atmosphere,
- wherein the lattice plane (0001) is oriented in a surface direction of the second surface and is exposed.
