Identification of active sites for highly efficient catalysts at the atomic scale water splitting is still a great challenge. Herein, we fabricate ultrathin nickel-incorporated cobalt phosphide porous nanosheets (Ni-CoP) featuring an heterometallic site (NiCo16–xP6) via boron-assisted method. The presence boron induces release-and-oxidation mechanism, resulting in gradual exfoliation hydroxide nanosheets. After subsequent phosphorization process, resultant Ni-CoP are implanted with...
The oxygen reduction reaction (ORR) on transition single-atom catalysts (SACs) is sustainable in energy-conversion devices. However, the atomically controllable fabrication of sites and sluggish kinetics ORR have remained challenging. Here, we accelerate acid through a direct O-O cleavage pathway using bi-functional ligand-assisted strategy to pre-control distance hetero-metal atoms. Concretely, as-synthesized Fe-Zn diatomic pairs carbon substrates exhibited an outstanding performance with...
Developing efficient and robust catalysts to replace Pt group metals for the oxygen reduction reaction (ORR) is conducive achieving highly energy conversion. Here, we develop a general ion exchange strategy construct ORR consisting of various atomically dispersed metal atoms anchored on N-doped porous carbon (M-SAs/NC) investigate atomic structure-catalytic activity relationship. The structure characterization results demonstrated that achieved varied due presence different centers....

Rational design and development of highly efficient hydrogen evolution reaction (HER) electrocatalysts is great significance for the green water electrolysis production technology. Ru-engineered 1D PtCo-Ptrich nanowires (Ru-Ptrich Co NWs) are fabricated by a facile electrodeposition method. The rich Pt surface on Pt3 contributes to fully exposed active sites enhanced intrinsic catalytic activity (co-engineered Ru atoms) HER. incorporation atoms can not only accelerate dissociation in...
