The design and development of inexpensive and highly efficient electrocatalysts for hydrogen production from water splitting are highly crucial for green energy and the hydrogen economy. Herein, we report phosphine reduced an iron-doped tungsten oxide nanoplate/reduced graphene oxide nanocomposite (Fe-WOxP/rGO) as an excellent electrocatalyst for the hydrogen evolution reaction. This electrocatalyst was synthesized using a hydrothermal method, followed by reduction with phosphine (PH₃), which was generated from sodium hypophosphite. The catalyst onset potential, Tafel slope, and stability were investigated. Accordingly, Fe-WOxP/rGO exhibited impressively high electrocatalytic activity with a low overpotential of 54.60 mV, which is required to achieve a current density of 10 mAcm⁻². The Tafel slope of 41.99 mV dec⁻¹and the linear sweep voltammetry curve is almost the same as 2000 cycles and electrolysis under static overpotential (54.60 mV) is remain for more than 24 h in 0.5 M H₂SO₄. The catalytic activity and conductivity of Fe-WOxP/rGO were higher than WO_XP, Fe-WOxP and WOxP/rGO. Such an outstanding performance of the Fe-WOxP/rGO nanocomposite is attributed to the coupled synergic effect between high oxygen vacancies formation on tungsten oxide in the nanoplate-like structure of Fe-WOxP and rGO nanosheet, making it as an excellent electrocatalyst for hydrogen evolution reaction.

用于水分解制氢的廉价和高效电催化剂的设计和开发对于绿色能源和氢经济至关重要。在本文中，我们报道了磷化氢还原了铁掺杂的氧化钨纳米板/还原的氧化石墨烯纳米复合材料（Fe-WOxP / rGO），这是一种极好的制氢反应的电催化剂。使用水热法合成该电催化剂，然后用次磷酸钠生成的膦（PH ₃）还原。研究了催化剂的起始电势，Tafel斜率和稳定性。因此，Fe-WOxP / rGO表现出令人印象深刻的高电催化活性，具有54.60 mV的低过电势，这是实现10 mAcm ^-2的电流密度所必需的。Tafel斜率41.99 mV dec ^-1和线性扫描伏安曲线几乎与2000次循环相同，并且在0.5 MH ₂ SO _4中在静态超电势（54.60 mV）下的电解保持超过24小时。Fe-WOxP / rGO的催化活性和电导率均高于WO _X P，Fe-WOxP和WOxP / rGO。Fe-WOxP / rGO纳米复合材料如此出色的性能归因于Fe-WOxP纳米板状结构中的氧化钨上高氧空位形成与rGO纳米片之间的耦合协同效应，使其成为极佳的析氢电催化剂。反应。
