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