Searching for efficient, low‐cost, and durable electrocatalysts toward the hydrogen evolution reaction (HER) is extremely urgent for future energy conversion systems. Herein, the colloidal synthesis of 2D tungsten‐doped nickel selenide nanosheets by using Ni(acac)2 (acac=aceylacetonate), [W(CO)6], and selenium powder as precursors in oleylamine is reported. The introduction of tungsten is essential for the formation of 2D nanosheets. As a result, by taking the advantage of the unique layered structure and strong synergistic electronic effect between nickel, tungsten, and selenium, the as‐synthesized Ni0.54W0.26Se nanosheets exhibit superior catalytic activity toward the HER in alkaline media, with an overpotential of 162 mV (η10), which is much lower than those of NiSe2 (η10=330 mV) and WSe2 (η10=378 mV), and higher than that of most previously reported selenide‐based electrocatalysts.

NiWSe 纳米片的胶体合成用于碱性介质中高效电催化析氢反应
对于未来的能源转换系统来说，寻找高效、低成本且耐用的析氢反应（HER）电催化剂至关重要。本文报道了使用 Ni(acac) 2 (acac=乙酰丙酮)、[W(CO) 6 ]和硒粉作为油胺中的前体，胶体合成二维钨掺杂硒化镍纳米片。钨的引入对于二维纳米片的形成至关重要。因此，利用镍、钨、硒之间独特的层状结构和强协同电子效应，合成的Ni 0.54 W 0.26 Se纳米片在碱性介质中对HER表现出优异的催化活性，具有超电势162 mV ( η 10 )，远低于 NiSe 2 ( η 10 = 330 mV) 和 WSe 2 ( η 10 = 378 mV)，并且高于大多数先前报道的硒基电催化剂。
