Abstract: This paper provides a review of the research progress in catalytic systems for low-temperature CO2 methanation，which focuses onthedetail discussion of theregulation efectofsupports，promoters，and metals as active species on catalyst performance.In conventional catalytic systems，Ni-based catalysts have been widely studied due to their excellent activity and low cost. For example，the modified Mn⋅Ni/Al2O3 catalyst could achieve a CO2 conversion of 88.9% and a CH4 selectivity close to 100% at a reaction temperature of 220‰ .Secondly，in terms of new catalytic technologies，the paper provides a detailed overview of recent advances in plasma-catalytic synergetic systems and photothermal catalyst. By activating CO2 molecules through non-thermal plasma technology，the activation energy of the reaction can be significantly reduced.For example，inthe plasma-catalytic synergetic system，the Ni/Al2O3 catalyst could achieve a CO2 conversion of 60% and a CH4 selectivity of 97% at a reaction temperature of 150qC . In addition， the introduction of photo-thermal catalytic technology further expands thereaction pathways forlow-temperature CO2 methanation.TheNiFeM（ M=Al ,Zr,Mg,Cr）catalyst could achieve a CO2 conversion up to 98% and a CH4 selectivity of 99% under light illumination.The introduction of these novel technologies offersa broader application prospect for low-temperature CO2 methanation.Finally，based on the current esearch status，the paper provides an outlook on the future development direction of the low-temperature CO2 methanation field，which clarifies thekey scientific challengesand technical dificulties that need to be addressed and offers the valuable insights for further research in this area.
