Abstract：With the rapid development of the world economy,energy scarcity and environmental pollution have become focal points of con-cern.The rapid consumption of fossil fuels has led to the continuous enhancement of the green house effect,causing severe impacts on global environment and climate.Utilizing abundant and clean solar-driven approaches can rapidly target heating supply,converting two major greenhouse gases(CH4/CO2)into valuable syngas under mild conditions,thereby significantly reducing the energy consumption and carbon emissions generated by traditional thermocatalytic processes.However,the current solar-driven dry reforming syngas technology still faces several challenges on its path towards industrial application,including low conversion rates of reactant molecules,low efficiency of solar-to-chemical energy conversion,catalyst sintering,and catalyst deactivation caused by carbon deposition.This paper focused on the in-herent characteristics of dry reforming reactions and the common issues in the field of solar thermal research,detailing the research progress on photo-thermal dry reforming reactions concerning catalyst preparation,support construction,reactor and system establishment,and opti-mization.Finally,the prospects and challenges of solar-driven photo-thermal catalytic dry reforming systems were discussed.
