Bismuth vanadate (BiVO4) has been widely investigated as a photocatalyst or photoanode for solar water splitting, but its activity is hindered by inefficient cocatalysts and limited understanding of the underlying mechanism. Here we demonstrate significantly enhanced oxidation on particulate BiVO4 via in situ facet-selective photodeposition dual-cocatalysts that exist separately metallic Ir nanoparticles nanocomposite FeOOH CoOOH (denoted FeCoOx), revealed advanced techniques. The mechanism...
Electrocatalytic hydrogen peroxide (H2 O2 ) synthesis via the two-electron oxygen reduction reaction (2e ORR) pathway is becoming increasingly important due to green production process. Here, cationic vacancies on nickel phosphide, as a proof-of-concept regulate catalyst's physicochemical properties, are introduced for efficient H2 electrosynthesis. The as-fabricated Ni (VNi )-enriched Ni2-x P-VNi electrocatalyst exhibits remarkable 2e ORR performance with molar fraction of >95% and Faradaic...
For electrochemical energy conversion, highly efficient and inexpensive electrocatalysts are required, which principally designed synthesized by virtue of structural regulations. Herein, we propose a rational linker scission approach to induce lattice strain in metal–organic framework (MOF) catalysts partially replacing multicoordinating linkers with nonbridging ligands. Strained NiFe-MOFs 6% expansion exhibit superior catalytic performance for the oxygen evolution reaction (OER) under...
Transition-metal sulfides are investigated as promising electrocatalysts for oxygen evolution reaction (OER) in alkaline media; however, the real active species remain elusive and development of oxyhydroxides reconstructed from delivering stable large current density at low applied potentials is a great challenge.

Abstract The homogeneity of single-atom catalysts is only to the first-order approximation when all isolated metal centers interact identically with support. Since realistic support various topologies or defects offers diverse coordination environments, realizing real requires precise control over anchoring sites. In this work, we selectively anchor Ir single atoms onto three-fold hollow sites (Ir 1 /T O –CoOOH) and oxygen vacancies /V on defective CoOOH surface investigate how modulate...
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.
