Remarkable hydrogen evolution reaction (HER) or superior oxygen (OER) catalyst has been applied in water splitting, however, utilizing a bifunctional for simultaneously generating H2 and O2 is still challenging issue, which crucial improving the overall efficiency of electrolysis. Herein, inspired by superiority carbon conductivity, propitious H atom binding energy metallic cobalt, better OER activity cobalt oxide, we synthesized cobalt–cobalt oxide/N-doped hybrids (CoOx@CN) composed Co0,...
The earth-abundant nanohybrids Co0/Co3O4@N-doped carbon nanotubes were fabricated via an efficient thermal condensation of d-glucosamine hydrochloride, melamine, and Co(NO3)2·6H2O. hybrids furnish excellent catalytic activity perfect chemoselectivity (>99%) for a wide range substituted nitroarenes (21 examples) under relatively mild conditions. high performance durability is attributed to the synergistic effects between each component, unique structure graphene layers-coated Co0, electronic...

Abstract Designing a facile strategy to access active and atomically dispersed metallic catalysts are highly challenging for single atom (SACs). Herein, simple fast approach is demonstrated construct Pt with atoms in large quantity via ball milling precursor N‐doped carbon support (K 2 PtCl 4 @NC‐M; M denotes ball‐milling). The as‐prepared K @NC‐M only requires low overpotential of 11 mV exhibits 17‐fold enhanced mass activity the electrochemical hydrogen evolution compared commercial 20 wt%...
The soft template method is broadly applied to the fabrication of hollow-structured nanomaterials. However, due instability and typical spherical shape these templates, resultant particles have a morphology with wide size distribution. Herein, we developed sustainable route fabricate asymmetric flasklike hollow carbonaceous structures highly uniform narrow distribution using method. A dynamic growth mechanism induced by synergetic interactions between biomass proposed. precursors (ribose)...
Abstract Metal single‐atom (SA) catalysts have attracted immense attention due to the high catalytic efficiency given by desired coordination environment of each metal atom. Yet, engineering local electronic structure SAs and multi‐atoms (MAs) still remains a challenge. Herein, an atomically dispersed catalyst comprised Pt SAs, Pt‐Pt/V dual‐atoms, small clusters supported on vanadium nitrogen co‐doped carbon (VNC) (denoted as Pt@VNC) surface is synthesized. In Pt@VNC, both V atoms are evenly...
Metallic Co promoted the phase transformation of β-WN to δ-WN. δ-WN exhibited superior HER performance compared β-WN.
Tungsten carbide (WC) materials have exhibited platinum-like catalytic behavior in many fields, whereas the adsorption of pure tungsten for H is too strong and demonstrates low activity hydrogen evolution reaction (HER). Herein, we successfully introduced transition metal into WC lattice optimized electron structure around Fermi level (EF) via facile annealing CoW-based metal–organic framework precursors. X-ray diffraction, photoelectron spectroscopy, absorption fine verified incorporation...
