Low-cost and CO2-free energy must be considered in the process to convert CO2 into renewable energy or chemicals. The conversion of CO2 to hydrocarbons by photocatalyst can reduce CO2 emission and generate renewable energy. This proposal will develop a process to reduce CO2 that includes to assemble the photoreaction system, to perform photocatalytic CO2 reaction, to measure the products, to prepare photocatalysts and to estimate photo efficiency. In addition, we will develop a photo hydrogenation of CO2 using different photocatalysts, pressure, temperature and residence time to achieve high-efficiency CO2 conversion to hydrocarbons. The experiment includes the analysis of formic acid and methanol. We will complete (1) the system of CO2 photoreaction and measurement methods, literature survey and patent analysis, (2) the photoreaction of CO2 with H2O, and (3) the photoreaction of CO2 with H2 in aqueous solution by measuring formic acid and methanol. Finally the evaluation of the photocatalysts performance and final report should be finished in one year.光觸媒二氧化碳光催化氫化太陽能PhotocatalystCO2photo hydrogenationsolar energy
