Numerous efforts have been made to search for high-efficiency and noble-metal-free electrocatalysts for the hydrogen evolution reaction (HER). In this work, molybdenum phosphide (MoP) nanoparticles encapsulated in P-doped carbon (MoP@PC) was synthesized through a facile one-step pyrolysis of the precursor, namely 3D cross-linked network structure of MoO_x contained in polyaniline and phytic acid (MoO_x@PANI-PA). The obtained MoP@PCelectrocatalyst retained the 3D structure and exhibits outstanding HER abilities with ultra-low overpotential (η₁₀ = 69 mV), small Tafel slope (55 mV dec⁻¹) and high stability in acid solution. This work offers a facile method to prepare cost-effective transition metal phosphide catalysts.

为了寻找用于氢释放反应（HER）的高效和无贵金属的电催化剂，已经进行了许多努力。在这项工作中，通过对前体进行简便的一步热解，即聚苯胺和植酸中包含的MoO _x的3D交联网络结构，来合成封装在P掺杂碳（MoP @ PC）中的磷化钼（MoP）纳米颗粒。（MoO _x @ PANI-PA）。将所得的MoP @ PCelectrocatalyst保持的3D结构和呈现突出她的能力具有超低过电位（η ₁₀ = 69毫伏），小塔菲尔斜率（55毫伏癸^-1）和高稳定性在酸溶液中。这项工作为制备具有成本效益的过渡金属磷化物催化剂提供了一种简便的方法。
