Preparation and characterization of photocatalyst for the conversion of co2 to methanol

Due to the reliance of the world on fossil fuel as major source of energy, the CO2 emission to the environment is inevitable which is responsible for global warming. Photocatalytic reduction of CO2 to fuel, such as methanol, methane etc. is a promising way to address the CO2 emission and energy cris...
