Abstract Transition metal chalcogenides have been identified as low-cost and efficient electrocatalysts to promote the hydrogen evolution reaction in alkaline media. However, identification of active sites underlying catalytic mechanism remain elusive. In this work, we employ operando X-ray absorption spectroscopy near-ambient pressure photoelectron elucidate that NiS undergoes an in-situ phase transition intimately mixed Ni 3 S 2 NiO, generating highly synergistic dual at /NiO interface....
Electrosynthesis of NH3 from nitrate anion (NO3–) reduction (NO3–RR) is a cascade reaction, which considered great potential alternative to the Haber–Bosch route reduce CO2 emissions and alleviate adverse effects excessive NO3– contamination in environment. Frequently, solid solution alloys (SSAs) with single-phase active site may struggle fully utilize their benefits during entire process reduction, involves multiple intermediate reactions. In this study, we showed that by separating Cu Ni...
This work reports a systematical study on the relationship of electronic structure to oxygen evolution reaction (OER) activity NixCo3–xO4 (x = 0–1) mixed oxides. The specific OER is substantially increased by 16 times from 0.02 mA cm–2BET for pure Co3O4 0.32 x 1 at an overpotential 0.4 V and exhibits strong correlation with amount Ni ions in +3 oxidation state. X-ray spectroscopic reveals that inclusion Ni3+ upshifts occupied valence band maximum (VBM) 0.27 eV toward Fermi level (EF),...
Double perovskite oxides are one of the most promising bifunctional electrocatalysts for efficient oxygen evolution reaction (OER) and reduction (ORR) due to their adjustable electronic structures via doping with different metal cations or engineering defects.

Abstract Identification of active sites in catalytic materials is important and helps establish approaches to the precise design catalysts for achieving high reactivity. Generally, conventional heterogeneous can be single atom, nanoparticle or a metal/oxide interface. Herein, we report that reverse interfaces also which are created from coordinated migration metal oxide atoms. As an example, Pd 1 /CeO 2 single-atom catalyst prepared via atom trapping, otherwise inactive at 30 °C, able...

Perovskite oxides have emerged as promising candidates for the oxygen evolution reaction (OER) electrocatalyst due to their flexible lattice structure, tunable electronic superior stability, and cost-effectiveness. Recent research studies mostly focused on traditional methods tune OER performance, such cation/anion doping, A-/B-site ordering, epitaxial strain, vacancy, so forth, leading reasonable yet still limited activity enhancement. Here, we report a novel strategy promoting perovskite...
