A Review on Photocatalytic Conversion Process of CO2 to Methanol

Global warming caused by greenhouse gases is one of the main environmental threats that we face in the 21st century. With increasing concerns, research on converting CO2 in to valuable compounds has increased. In the past few decades, scientific consensus for capture, fixation and recycling technologies of CO2 increased. Today, methanol production, as one of the hydrocarbons that can be used in various industries instead of crude oil derivatives, is very important. Photo Catalytic conversion of CO2 into valuable compounds, in addition to reduce concerns about this pollutant, is a new way to produce synthetic compounds derived from carbon dioxide gas.
In this review paper, after presenting the different methods of application and conversion for CO2, photo catalytic conversion process will have been studied and then catalysts, the required reactions as well as the types of reactors will have been discussed.
