开发廉价、高效的酸性和碱性介质中的析氢反应电催化剂对氢能工业具有重要意义。据此，我们利用大豆分离蛋白（C源和N源）和植酸（掺杂剂和磷化剂）对钴离子的螯合能力，制备了组成均匀的前驱体混合物，并在800 °C下通过碳化一步合成构建了Co2 P/N-P共掺杂多孔碳复合材料。合成的Co 2 P/NPPC-800电催化剂在0.5 M H2 SO 4和1.0 M KOH中10 mA cm −2时表现出较低的HER过电位，分别为121和125 mV，接近商业Pt/C催化剂的HER过电位。此外，在Co2 P/NPPC-800复合材料表面包覆NPPC基体，可以有效地降低复合材料在HER过程中的腐蚀，且具有良好的稳定性和耐久性.此外，该工作提供了一个方便的合成策略磷化物/掺杂多孔碳复合材料在其他电化学能源技术。·采用新的策略实现了Co2 P/N-P共掺杂多孔碳复合材料。·在碱性和酸性介质中，Co2 P/NPPC均表现出良好的HER活性。·Co2 P在NPCC上的锚定作用有利于NPCC的稳定性和耐久性。该合成策略具有成本效益高、操作简单、环境友好和可参考性等特点。
Developing inexpensive and efficient electrocatalysts for hydrogen evolution reaction (HER) in both acidic and alkaline mediums is of great significance to the hydrogen energy industry. Hereby, we prepared a mixture of precursors with homogeneous composition by using the chelating ability of soybean protein isolate (C and N source) and phytic acid (dopant and phosphating agent) with cobalt ions, and achieved one-step synthesis and construction of Co 2 P/N–P co-doped porous carbon composite by carbonization at 800 °C. The as-synthesized Co 2 P/NPPC-800 electrocatalyst exhibits low HER overpotentials of 121 and 125 mV at 10 mA cm −2 in 0.5 M H 2 SO 4 and 1.0 M KOH, which are close to those of the commercial Pt/C catalyst. Additionally, the NPPC substrate surrounding the Co 2 P could diminish the corrosion during the HER, and Co 2 P/NPPC-800 displays good stability and durability. Furthermore, this work offers a convenient synthesis strategy for phosphide/doped porous carbon composites in other electrochemical energy technologies. • A new strategy achieved Co 2 P/N–P co-doped porous carbon composite. • The obtained Co 2 P/NPPC exhibited good catalytic HER in alkaline and acidic mediums. • The anchoring of Co 2 P on the NPCC was beneficial for the stability and durability. • The synthesis strategy was cost-effective, simple, eco-friendly and referenceable.
