Based on the thermodynamics and reac-tion mechanism of CH4-CO2 dry reforming(DRM)reaction,the control technologies to avoid Ni based catalyst coking and sintering,as well as the applica-tion technologies of plasma catalyst coupling and photothermal synergistic catalysis for DRM were summarized with 31 references from the aspects of Ni particle size,spatial confinement structure,forma-tion of oxygen vacancies,and increase of active oxy-gen species.The development direction of DRM technology was prospected.It was pointed out that the use of renewable electricity to synergistically de-velop plasma and photothermal catalysis for DRM technology had good development prospects.
