摘要
纳米结构中的晶格应变作为基础研究课题的势头日益增强。可以设计纳米颗粒的表面晶格以产生应变或者其他结构变化,使其原子位置偏离正常的晶格点,进而影响纳米颗粒的电子结构和催化性能。本文首先介绍了金属纳米粒子的不同应变源,重点介绍了不同应变基本结构的合成。讨论了晶格应变的表征手段及其在催化领域应用的研究进展。最后介绍了应变金属纳米颗粒合成和催化应用所面临的挑战,并对未来的研究方向进行了展望。
Lattice strain in nanostructures is gaining momentum as a basic research topic.The surface lattice of the nanoparticle can be designed to produce strain or other structural changes,so that the atomic position deviates from the normal lattice point,thereby affecting the electronic structures and catalytic properties of the nanoparticle.This review first describes the different sources of strain in metal nanoparticles,highlighting the synthesis of the differently strained basic architectures.The characterization and catalytic applications of lattice strain are then discussed.Finally,several of the challenges facing the synthesis and catalysis by strained metal nanoparticle architectures are described.
