Method of reducing carbon dioxide using the carbon dioxide reduction for photochemical electrode , and the optical chemical electrodes

摘要

In the present invention uses an anode electrode having a nitride semiconductor layer. The nitride semiconductor layer, Al _x Ga _1-x N layer (0 x 0.25), Al _y Ga _1-y N layer (0 y x), and comprises a GaN layer, Al _y Ga _1-y N layer, It said Al _x Ga _1-x has been sandwiched between the N layer and the GaN layer, Al _x Ga _{1- x} values of x along the thickness direction of the N layer is constant, the value of y, Al _x Ga _1-x GaN layer from the layer It has decreased in the direction to. Al _x Ga _1-x layer is irradiated with light having a wavelength below 360nm, reducing dioxide oxygen.
