Title:
CARBON DIOXIDE REDUCTION ELECTRODE AND CARBON DIOXIDE REDUCTION DEVICE IN WHICH SAME IS USED
Document Type and Number:
WIPO Patent Application WO/2015/133127
Kind Code:
A1
Abstract:
Provided are a CO2 reduction electrode and a CO2 reduction device making it possible to sufficiently obtain a reduction product comprising organic matter, etc. The reduction electrode (1) has an electroconductive substrate (11), a p-type optical semiconductor (12) provided thereon, and an n-type optical semiconductor (13) provided on the p-type optical semiconductor (12). The reduction electrode (1) is used in the reduction device (8). The energy level of the conduction band of the p-type optical semiconductor (12) is higher in the negative direction than the energy level of the conduction band of the n-type optical semiconductor (13). The energy level of the valence band of the p-type optical semiconductor (12) is higher in the negative direction than the energy level of the valence band of the n-type optical semiconductor (13).
