Increasing CO2 emission is considered as main cause of global warming by greenhouse effect. So, numerous research have been carried out to solve the CO2 problems by various direction such as thermochemical, electrochemical, and biochemical pathways. However, direct conversion of CO2 to a valuable chemicals by photocatalytic pathway is eventual and effective resolution in term of economy and environment. In previous study, we developed ZnO-Cu2O hybrid nanocatalyst. Our catalyst shows high activity and selectivity in aqueous solution but in this condition has many problems such as large amount CO2 dissolving and catalyst stability affected by pH of the solution. In this study, we conducted photocatalytic reaction in gas-phase CO2. In this condition, we can easily control many reaction factors such as pressure of CO2, temperature of reactor and H2O vapor amounts. So, we can obtained increased activity and stability by control the reaction factors. Additionally, in comparison with aqueous-phase reaction, ZnO-Cu2O catalyst shows distinct selectivity.
