The phase of nanocrystals has a key role in the modulation of catalytic properties. Uniform and well‐crystallized nickel phosphide nanocrystals with controlled phases (Ni5P4, Ni2P, and Ni12P5) and narrow size distributions are synthesized by a wet chemical method. The phases of the as‐synthesized nickel phosphide nanocrystals are controlled by the P/Ni precursor molar ratio, heating process, and time...
Tungsten‐based catalysts are promising candidates to generate hydrogen effectively. In this work, a single‐W‐atom catalyst supported on metal–organic framework (MOF)‐derived N‐doped carbon (W‐SAC) for efficient electrochemical hydrogen evolution reaction (HER), with high activity and excellent stability is reported. High‐angle annular dark‐field scanning transmission electron microscopy (HAADF‐STEM)...
