Abstract Highly efficient and stable catalysts for the hydrogen evolution reaction, especially in alkaline conditions are crucial practical demands of electrochemical water splitting. Here, synthesis a novel RuAu single‐atom alloy (SAA) by laser ablation liquid is reported. The SAA exhibits high stability low overpotential, 24 mV@10 mA cm −2 , which much lower than that Pt/C catalyst (46 mV) media. Moreover, turnover frequency three times catalyst. Density functional theory computation...

Single-atom catalysts based on metal-N4 moieties and anchored carbon supports (defined as M-N-C) are promising for oxygen reduction reaction (ORR). Among those, M-N-C with 4d 5d transition metal (TM4d,5d) centers much more durable not susceptible to the undesirable Fenton reaction, especially compared 3d ones. However, ORR activity of these TM4d,5d-N-C is still far from satisfactory; thus far, there few discussions about how accurately tune ligand fields single-atom TM4d,5d sites in order...
2D perovskites, due to their unique properties and reduced dimension, are promising candidates for future optoelectronic devices. However, the development of stable nontoxic wide-bandgap perovskites remains a challenge. all-inorganic perovskite Sr2 Nb3 O10 (SNO) nanosheets with thicknesses down 1.8 nm synthesized by liquid exfoliation, first time, UV photodetectors (PDs) based on individual few-layer SNO sheets investigated. The sheet-based PDs exhibit excellent detecting performance...
Exploration of earth-abundant transition-metal sulfide electrocatalysts with Pt-like activity toward alkaline hydrogen evolution reaction (HER) is significant for future global energy supply but still a challenge. Herein, we rationally designed and fabricated self-supported F-anion-doped Ni3S2 nanosheet array grown on Ni foam (F–Ni3S2/NF) enhanced HER performance in media.

Iron–nickel sulfide ((Ni,Fe)3S2) is one of the most promising bifunctional electrocatalysts for both hydrogen evolution reaction (HER) and oxygen (OER) in alkaline media because their metallic conductivity low cost. However, reported HER activity (Ni,Fe)3S2 still unsatisfactory. Herein, three-dimensional self-supported phosphorus-doped nanosheet arrays on Ni foam (P-(Ni,Fe)3S2/NF) are synthesized by a simple one-step simultaneous phosphorization sulfuration route, which exhibits dramatically...
The oxygen evolution reaction is known to be a kinetic bottleneck for water splitting. Triggering the lattice oxidation mechanism (LOM) can break theoretical limit of conventional adsorbate and enhance kinetics, yet unsatisfied stability remains grand challenge.

The obtained showed multicomponents, high polarity, more active...
Abstract Atomically dispersed 3D transitional metal active sites with nitrogen coordination anchored on carbon support have emerged as a kind of promising electrocatalyst toward oxygen reduction reaction (ORR) in the field fuel cells and metal–air cells. However, it is still challenge to accurately modulate structure single‐atom sites, especially first‐shell coordination, well identify relationship between geometric/electronic ORR performance. Herein, carbon‐supported nickel catalyst...
Bimetallic layered double hydroxides (LDHs) are promising catalysts for anodic oxygen evolution reaction (OER) in alkaline media. Despite good stability, NiCo LDH displays an unsatisfactory OER activity relative to the most robust NiFe and CoFe LDH. Herein, a novel electrocatalyst modified with single-atom silver grown on carbon cloth (AgSA -NiCo LDH/CC) that exhibits exceptional stability 1.0 m KOH is reported. The AgSA LDH/CC catalyst only requires low overpotential of 192 mV reach current...
