Photocatalytic Reduction of CO2 With Solvent on Alumina Supported With Tio2

Carbon dioxide accounts for the largest share of the world’s greenhouse gas emissions. There is a growing need to mitigate CO2 emissions. One of the strategies to mitigate CO2 emissions is using CO2 as a raw material in chemical processes. Reactions involving CO2 typically required high energy input...
