The coordinated configuration of atomic platinum (Pt) has always been identified as an active site with high intrinsic activity for hydrogen evolution reaction (HER). Herein, we purposely synthesize single vacancies in a carbon matrix (defective graphene) that can trap Pt to form the Pt-C3 configuration, which gives exceptionally reactivity HER both acidic and alkaline solutions. is valued turnover frequency (TOF) 26.41 s-1 mass 26.05 A g-1 at 100 mV, respectively, are nearly 18 times higher...
Abstract Atomic metal catalysis (AMC) provides an effective way to enhance activity for the oxygen reduction reaction (ORR). Cobalt anchored on nitrogen‐doped carbon materials have been extensively reported.

Manipulating the surface structure of electrocatalysts at atomic level is primary importance to simultaneously achieve activity and stability dual-criteria in oxygen reduction reaction (ORR) for proton exchange membrane fuel cells.

Abstract Metal–organic framework (MOFs) two‐dimensional (2D) nanosheets have many coordinatively unsaturated metal sites that act as active centres for catalysis. To date, limited numbers of 2D MOFs can be obtained through top‐down or bottom‐up synthesis strategies. Herein, we report a oxide sacrifice approach (2dOSA) to facilely synthesize ultrathin MOF‐74 and BTC MOF with flexible combination sites, which cannot the delamination their bulk counterparts (top‐down) conventional solvothermal...
Selective electrocatalytic nitrate-to-ammonia conversion holds significant potential in treatment of nitrate wastewater and simultaneously produces high-value-added ammonia.

Herein, a series of carbocatalysts containing Ru-based clusters have been prepared by the assistance zeolite–imidazolate frameworks (ZIFs). The introduction Ru is based on adsorption well-defined Ru3(CO)12 within cavity ZIFs following decomposition at 900 °C. Moreover, without breaking skeleton and porosity ZIFs, as-generated species would bond with Co nodes in situ to form bimetallic Ru–Co if Co-bearing metal–organic were utilized as host. Within confined space assembly could be rationally...
Abstract The oxygen vacancies of defective iron–cobalt oxide (FeCoO x ‐Vo) nanosheets are modified by the homogeneously distributed sulfur (S) atoms. S atoms can not only effectively stabilize (Vo), but also form Co−S coordination with Co active site in Vo, which modulate electronic structure site, enabling FeCoO ‐Vo‐S to exhibit much superior OER activity. exhibits a mass activity 2440.0 A g −1 at 1.5 V vs. RHE 1.0 m KOH, 25.4 times higher than that RuO 2 . Tafel slope is as low 21.0 mV dec...
Metal-free oxygen reduction reaction (ORR) catalysts have been intensively studied during the past decade. For heteroatom-modified carbon materials, influence of heteroatoms on ORR remains unclear. Here, we use computational simulations to probe role in catalyzing ORR; graphene with pentagonal (C5) defect is selected as a model catalyst this study. Both theoretical and experimental results demonstrate that N S co-doped graphenes without pentagons shows very poor performance; however,...
Industrial production of HCN from NH3 and CH4 not only uses precious Pt or Pt–Rh catalysts but also requires extremely high temperatures (∼1600 K). From an energetic, operational, safety perspective, a drastic decrease in temperature is highly desirable. Here, we report ammonia reforming methane for the H2 at 673 K by combination CH4/NH3 plasma supported Cu/silicalite-1 catalyst. 30% conversion has been achieved with 79% selectivity. Catalyst characterization diagnostics reveal that...
