在当前能源短缺和环境污染下，氢能源作为一种极具潜在价值的新能源而广受关注，其中电解水析氢反应(HER)成为获得氢能源的一种有效途径。然而高效Pt、Ru等贵金属电催化剂储量低、成本高，限制了其大规模使用。基于此，本文以MoO₃纳米带为基底，通过弱碱刻蚀和高温煅烧并通过P掺杂合成了一种具有分级纳米片管状结构的低成本高效非贵金属催化剂P-NiMoO₄，得益于这种分级纳米结构和P的掺杂，该催化剂在酸性和碱性条件中均表现出良好的HER性能和循环稳定性。当电流密度为10 mA cm^？2时，在0.5 M H₂SO₄和1 M KOH下的过电位分别为133 mV和95 mV；在200 mA cm^？2处的过电位分别为322 mV和342 mV，甚至可以和商业的Pt/C催化剂相媲美。
Under the current energy shortage and environmental pollution, hydrogen energy is widely concerned as a new energy source with great potential value, among which hydrogen electrolysis reaction (HER) has become an effective way to obtain hydrogen energy. However, the low reserves and high costs of noble metal electrocatalysts such as high-efficiency Pt and Ru limit their large-scale use. Based on this, a low-cost and efficient non-precious metal catalyst P-NiMoO₄ with a hierarchical nanosheet-tubular structure was synthesized by weak alkali etching and high-temperature calcination and doped by P. Thanks to this hierarchical nanostructure and P doping, the catalyst exhibited good HER performance and cycling stability in both acidic and alkaline conditions. At a current density of 10 mA？cm^？2, the overpotentials were 133 mV and 95 mV at 0.5 M H₂SO₄ and 1 M KOH, respectively, and 322 mV and 342 mV at 200 mA？cm^？2, respectively, which were even comparable to commercial Pt/C catalysts.
