Lattice strain in metallic nanomaterials and its applications in catalysis

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 deviate 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. Their characterization and catalytic applications are then discussed. Finally, several of the challenges facing the synthesis and catalysis by strained metal nanoparticle architectures are described.
