摘　　要：电催化CO_(2)技术能够利用可再生能源将CO_(2)还原为具有高附加价值的化学品,对缓解能源危机及控制碳平衡具有重要意义。然而,电催化CO_(2)反应动力学缓慢、机理复杂且催化效率不高,因此,高效催化剂一直是研究重点。HCOOH作为CO_(2)电催化还原产物之一,在燃料和化学工业中具有广泛的应用,Sn因其成本低、环境友好等优势成为该领域具有发展潜力的催化材料。介绍了常温常压水溶液体系中Sn基材料电催化CO_(2)为HCOOH的研究现状,分别从Sn金属、Sn合金、Sn氧化物及Sn硫化物4个方面总结了催化剂的特点和优势,并展望了Sn基催化剂的未来发展趋势。Electrocatalytic CO_(2) technology can utilize renewable energy to reduce CO_(2) to value-added chemical fuels,which is of great significance for alleviating the energy crisis and controlling carbon balance.However,the slow reaction kinetics of electrocatalytic CO_(2) and the complex reaction mechanism result in the low catalytic efficiency,therefore,highly active catalysts have always been the focus of research.As one of the electrocatalytic reduction products of CO_(2),formate has a wide range of applications in the fuel and chemical industries,and Sn-based materials have become catalysts with great development potential because of their low cost and environmental friendliness in the catalysts for the electrocatalytic CO_(2) to HCOOH.The current research on the electrocatalysis of CO_(2) to formate HCOOH by Sn-based materials in a normal temperature and pressure aqueous solution system is described,the four aspects including Sn-based metal,Sn-based alloy,Sn-based oxide,and Sn-based sulfide are reviewed,the characteristics and advantages of the catalysts are summarized,and the future development trends of Sn-based catalysts are discussed.
