摘要:

以生物大分子為核心的仿生礦化法是近年來合成生物無機復合納米材料的研究熱點之一。作為一種多功能性生物分子，多肽不僅具有可設計性、可降解性和高生物相容性，而且在特定溶液微環境下可自組裝形成不同維度的納米結構，為可控合成不同結構和功能的納米材料，尤其是貴金屬納米催化材料，提供了合適的生物模板。因多肽組裝結構的空間限域及其與金屬納米粒子、反應底物之間的相互作用，使得負載貴金屬的多肽組裝體納米結構催化性能增強，在有機合成、電催化、光催化等領域有廣闊的應用前景。概述了多肽自組裝及其作為模板介導合成貴金屬納米結構的方法，及其在相關催化領域的應用，為新型納米催化材料開發提供新的研究思路。

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.
