Abstract

This report describes the results of effective fixing technique of CO2 by utilizing solar energy. First of all, the investigation was directed to the technique for synthesizing ethylene, hydrocarbons and alcohol by electrochemical reduction of CO2. The power required for this process is supplied by photovoltaic power generation. Development of excellent electrode catalyst is needed because the reduction of CO2 requires a high overvoltage. It is desirable to enhance the selectivity of the reaction for specific material and improve the transport process in the electrolytic cell. Next, designing of material and reaction of photocatalysts using semiconductor electrode and semiconductor particulate was examined. A semiconductor electrode made of FeS2 is inexpensive and has a high ability of collecting solar light. In the category of photocatalysis system, a photocatalytic system in which semiconductor particles are embedded in vesicle and a photpocatalyst based on potassium niobate are noteworthy. As biosystem, the method of reducing CO2 by calcareous algae which simultaneously advances fixing and calcification of CO2 by photosynthesis is noteworthy. 129 refs., 45 figs., 20 tabs.
