光エネルギーの利用方法および光エネルギーの利用装置

Document Type and Number:

Japanese Patent JP6388820

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a utilization method of light energy, which produces and collects high-purity oxygen at necessary place and time.SOLUTION: The utilization method of light energy comprises: an accumulation step of accumulating in an anode chamber 18 oxidation products such as persulfate ions generated from materials to be oxidized such as sulfate ions by a redox reaction, where the standard redox potential is more positive than +1.23 V (RHE), by applying light on an n-type semiconductor 26 on an anode electrode 22 installed in the anode chamber 18 of an electrolytic tank 12; and a reaction step of transferring the oxidized product accumulated in the anode chamber 18 into a vessel 14 different from the anode chamber 18, thereafter generating oxygen gas by decomposing the oxidized product, and collecting the oxygen gas generated. In a cathode chamber 20, hydrogen gas is generated from water.SELECTED DRAWING: Figure 1
