摘　　要：贵金属由于其独特的物理化学性质而被广泛应用于多个领域,但是其在地壳中储量较低、价格昂贵、单一组分易于团聚和烧结等缺点限制了其大规模催化应用.通过构建金属合金纳米晶和贵金属负载型催化剂可以有效解决上述问题.本文系统概述了贵金属/氧化铈纳米催化材料的控制合成和性能调控,结合本课题组的相关研究工作,主要介绍了特定形貌和纳米结构的双金属/三金属纳米催化剂和贵金属-氧化铈负载型催化剂的控制合成、结构对性能的影响以及它们在催化领域的应用进展.最后展望了关于贵金属/氧化铈纳米催化材料的前沿研究的发展前景.Noble metals are widely used in many fields,particularly in catalysis,due to their unique physical and chemical properties.However,their large-scale applications are limited,due to the high price,low reserves,easy agglomeration and the sintering of single component.The above problems can be effectively solved by constructing metal alloy nanocrystals and cerium oxide supported noble metal catalysts.In this review,we will summarize recent progress on the controlled synthesis and catalytic performances of noble metals/cerium oxide nanocatalysts.In detail,mainly based on our group’s work,we present the controlled synthetic approaches,the relationship between the structures and properties,and the catalytic applications of those catalysts with specific shapes and nanostructures.Finally,the future developments and challenges of the cutting-edge research on noble metal-based catalysts are prospected.
