Abstract Fe–N–C catalysts are emerging as promising alternatives to Pt‐based for the oxygen reduction reaction (ORR), while they still suffer from sluggish kinetics due discontented binding affinity between Fe‐N 4 sites and oxygen‐containing intermediates, unsatisfactory stability. Herein, a flexible multichannel carbon fiber membrane immobilized with atomically dispersed neighboring Fe nanoclusters/nanoparticles (FeN ‐Fe NCP @MCF) is synthesized. The optimized geometric electronic...
Abstract It is important to tune the coordination configuration of dual‐atom catalyst (DAC), especially in first sphere, render high intrinsic catalytic activities for oxygen reduction/evolution reactions (ORR/OER). Herein, a type atomically dispersed and boron‐coordinated DAC structure, namely, FeN 4 B‐NiN B dual sites, reported. In this incorporation boron into sphere /NiN atomic sites regulates its geometry electronic structure by forming “Fe‐B‐N” “Ni‐B‐N” bridges. The exhibits much...
Strain in layered transition-metal dichalcogenides (TMDs) is a type of effective approach to enhance the catalytic performance by activating their inert basal plane. However, compared with traditional uniaxial strain, influence biaxial strain and TMD layer number on local electronic configuration remains unexplored. Herein, via new situ self-vulcanization strategy, biaxially strained MoS2 nanoshells form single-crystalline Ni3 S2 @MoS2 core-shell heterostructure are realized, where precisely...
The sluggish kinetics of Volmer step in the alkaline hydrogen evolution results large energy consumption. challenge that has yet well resolved is to control water adsorption and dissociation. Here, we develop biaxially strained MoSe2 three dimensional nanoshells exhibit enhanced catalytic performance with a low overpotential 58.2 mV at 10 mA cm−2 base, long-term stable activity membrane-electrode-assembly based electrolyser 1 A cm−2. Compared flat uniaxial-strained MoSe2, establish stably...
Abstract Oxygen reduction reaction (ORR) and the oxygen evolution (OER) are key reactions in diverse energy conversion devices, highlighting importance of efficient catalysts. Edge‐anchored single atom catalysts (E‐SACs) emerge as a special class atomic structure, but detailed configuration its correlation with catalytic activity remain little explored. Herein, total 78 E‐SACs (E‐TM‐N x ‐C) have been constructed based on 26 transition metal (TM) species three coordination patterns. Using...
Designing efficient and cost-effective electrocatalysts is crucial for the large-scale development of sustainable hydrogen energy. Amorphous catalysts hold great promise application due to their structural flexibility high exposure active sites. We report a novel method in situ growth amorphous CoNiRuOx nanoparticle structures (CoNiRuOx/NF) on nickel foam substrate. In 1 m KOH, CoNiRuOx/NF achieves current density 10 mA/cm2 with evolution reaction (HER) overpotential only 43 mV remains...
The structure-performance relationship for single atom catalysts has remained unclear due to the averaged coordination information obtained from most single-atom catalysts. Periodic array of atoms may provide a platform tackle this inaccuracy. Here, we develop data-driven approach by incorporating high-throughput density functional theory computations and machine learning screen candidates based on library 1248 sites anchored biaxial-strained transition metal dichalcogenides. Our screening...
