Photocatalytic technology mainly use semiconductor materials to absorb solar light to produce electrons and holes,which migrate to the surface of semiconductor materials to directly or indirectly conduct redox reactions with adsorbent reactants.Photocatalytic technology is widely used in petrochemical industry,which mainly involves petrochemical reaction,waste gas treatment,wastewater treatment,solid waste treatment and soil remediation.Solar energy resource is abundant and widely distributed,the application of photocatalytic technology with mild reaction conditions in petrochemical industry can effectively reduce the consumption of fossil fuels,which is of great benefit to achieving the"Dual-Carbon"goal.
