Developing low-cost electrocatalysts for efficient hydrogen evolution in both acidic and alkaline conditions is crucial for water-electrolytic hydrogen applications. Herein, MoP was synthesized via a simple, low-cost, and green phosphorization route. More importantly, the Ru/MoP composite prepared using the as-synthesized MoP as a reactant, which exhibited excellent catalytic activity for the hydrogen evolution reaction. It showed lower overpotentials of 108 and 55 mV at 10 mA·cm in acidic and alkaline solutions, respectively, which are superior to those of bare Ru and pristine MoP as well as comparable or even better than those of previously reported excellent Ru- or MoP-based catalysts. In addition, it also demonstrated small Tafel slopes of 52.6 mV dec and 67.9 mV dec in acidic and alkaline solutions, respectively, along with long-term stability. This work provides an effective and feasible route to design high-efficient MoP-based electrocatalysts for hydrogen evolution reaction.
开发在酸性和碱性条件下均能高效析氢的低成本电催化剂对于水电解制氢应用至关重要。在此，通过一种简单、低成本且绿色的磷化路线合成了MoP。更重要的是，以合成的MoP作为反应物制备的Ru/MoP复合材料对析氢反应表现出优异的催化活性。在酸性和碱性溶液中，其在10 mA·cm时的过电位分别为108和55 mV，低于裸Ru和原始MoP，并且与先前报道的优异的Ru基或MoP基催化剂相当甚至更好。此外，它在酸性和碱性溶液中的塔菲尔斜率分别为52.6 mV dec和67.9 mV dec，同时具有长期稳定性。这项工作为设计用于析氢反应的高效MoP基电催化剂提供了一条有效且可行的途径。
