Tensile‐Strained Palladium Nanosheets for Synthetic Catalytic Therapy and Phototherapy

“…Strain effect has been actively studied to stimulate the inactive surfaces of various catalysts. [ 13 ] By modulating the atomic distances to generate lattice strain, the d‐band center will be shifted, which can optimize the chemisorption, and in turn improve the catalytic performance. [ 14 ] Structural defect is an important source of lattice strain, [ 13 ] and surface reconstruction has been commonly used to introduce structural defect, [ 15 ] especially in electrocatalysis.…”

“…[13] By modulating the atomic distances to generate lattice strain, the d-band center will be shifted, which can optimize the chemisorption, and in turn improve the catalytic performance. [14] Structural defect is an important source of lattice strain, [13] and surface reconstruction has been commonly used to introduce structural defect, [15] especially in electrocatalysis. However, the lattice strain of noble metal nanomaterials induced by surface reconstruction has rarely been studied.In this work, we introduced lattice tensile strain into Pd NSs by surface reconstruction for nanozyme-based catalytic therapy and dual phototherapy.…”

Activating ruthenium dioxide via compressive strain achieving efficient multifunctional electrocatalysis for Zn‐air batteries and overall water splitting

“…Generally, the commonality of these approaches is to change the electronic structure of the atomic surface by adjusting or controlling the physical and chemical state of the catalyst surface, so as to simultaneously optimize the binding strength between different reaction intermediates (e.g., *H, *O, *OOH, and *OH) and active sites. Analogously, surface strain engineering has emerged as one of the most promising ways in precisely modulating the electronic configuration and altering binding energies toward adsorbates by the atomic‐scale structural deformation effects (lattice compressive or tensile strain) 15–26 . Recent studies have shown that the lattice strain can be maximized to tailor the d‐band orbital overlap and significantly alter the Gibbs adsorption/desorption free energy for reactive intermediates by modifying the distance between atoms, and thus efficiently stimulate the intrinsic activity of the catalyst in various electrochemical reactions (e.g., HER, OER, and ORR) 15–19,27–32 .…”
