The carbon dioxide reforming of methane(CRM)reaction under photothermal synergistic catalysis conditions couples the photo and thermal effects and can generate synthesis gas(CO and H_(2))at low temperatures,reducing carbon emissions and converting solar energy into chemical energy for storage,which is one of the effective strategies to achieve the dual carbon goal.The catalyst is the core of the photothermal synergistic catalysis for CRM reaction while regulating the structural properties of the thermal catalytic active centers(active metals)and the optical.properties of the light-absorbing materials(carriers),as well as the synergistic effects of the active components and the light-absorbing materials,to improve the thermal and photocatalytic performance of the photothermal synergistic catalysts simultaneously,which is one of the effective ways to develop efficient photothermal synergistic catalysts.This article reviewed the mechanism of photothermal synergistic catalysis CRM reaction and the latest research progress of related metal catalysts and semiconductor materials,and explored the future development trends.
