摘要:: 以生物大分子为核心的仿生矿化法是近年来合成生物无机复合纳米材料的研究热点之一。作为一种多功能性生物分子，多肽不仅具有可设计性、可降解性和高生物相容性，而且在特定溶液微环境下可自组装形成不同维度的纳米结构，为可控合成不同结构和功能的纳米材料，尤其是贵金属纳米催化材料，提供了合适的生物模板。因多肽组装结构的空间限域及其与金属纳米粒子、反应底物之间的相互作用，使得负载贵金属的多肽组装体纳米结构催化性能增强，在有机合成、电催化、光催化等领域有广阔的应用前景。概述了多肽自组装及其作为模板介导合成贵金属纳米结构的方法，及其在相关催化领域的应用，为新型纳米催化材料开发提供新的研究思路。

Abstract:: The biomimetic mineralization method with biological macromolecules as the core is one of the research hotspots in the synthesis of bio-inorganic composite nanomaterials in recent years. As a multifunctional biomolecule, peptides not only have designability, degradability and high biocompatibility, but also can self-assemble to form nanostructures of different dimensions in a specific solution microenvironment. Peptides can provide suitable biological templates for the controllable synthesis of nanomaterials with different structures and functions, especially noble metal nano catalytic materials. Due to the spatial limitation of the peptide assembly structure and its interaction with metal nanoparticles and reaction substrates, peptide based noble metal nanostructures have the characteristic of enhancing the catalytic reaction and have broad application prospects in the fields of organic synthesis, electrocatalysis and photocatalysis. In this review，we summarize the peptide self-assembly and discuss the application of peptides template-mediated noble metal nanostructures in catalysis, it will provide new research ideas for the development of new nano catalytic materials.
