Abstract It is vital to understand the oxygen reduction reaction (ORR) mechanism at molecular level for rational design and synthesis of high activity fuel‐cell catalysts. Surface enhanced Raman spectroscopy (SERS) a powerful technique capable detecting bond vibrations surface species in low wavenumber range, however, using it probe practical nanocatalysts remains extremely challenging. Herein, shell‐isolated nanoparticle‐enhanced (SHINERS) was used investigate ORR processes on bimetallic Pt...
The two-dimensional surface or one-dimensional interface of heterogeneous catalysts is essential to determine the adsorption strengths and configurations reaction intermediates for desired activities. Recently, development single-atom has enabled an atomic-level understanding catalytic processes. However, it remains obscure whether conventional concept mechanism are applicable zero-dimensional single atoms. In this work, we arranged locations atoms explore their interfacial interactions...
Vanadia-based catalysts have been widely used for catalyzing various reactions, including their long-standing application in the deNOx process. It has commonly considered that vanadium species dispersed on supports with a large surface area act as catalytically active sites. However, role of crystalline V2O5 selective catalytic reduction NOx NH3 (NH3-SCR) remains unclear. In this study, catalyst low vanadia loading was synthesized, which deposited TiO2 support had pretreated at high...
Abstract The metal-support interactions (MSI) could greatly determine the electronic properties of single-atom catalysts, thus affecting catalytic performance. However, typical approach to regulating MSI usually suffers from interference variation supports or sacrificing stability catalysts. Here, we effectively regulate site-specific Ir single atoms anchored on Ni layered double hydroxide through an electrochemical deposition strategy. Cathodic drives locate at three-fold facial center...
