Highly efficient and stable non‐noble metal electrocatalysts for hydrogen generation are desired for sustainable development of energy conversion and storage. Here, a facile low‐temperature phosphidation process is developed for phosphorus doping into molybdenum disulfide (MoS₂) nanosheets directly synthesized on carbon cloths to function as an integrated electrode for efficient hydrogen evolution reaction. The optimal phosphorus‐doped (3.3 at%) MoS₂ nanosheets exhibit substantially lower overpotentials of 133 and 189 mV to drive the current densities of 20 and 100 mA cm^‐2, respectively, as compared with undoped MoS₂, and an impressively small Tafel slope of 67.0 mV dec⁻¹. The excellent stability in acid media also makes the phosphorus‐doped MoS₂ nanosheet catalysts promising candidates for hydrogen generation in practical applications.

碳布上负载的磷掺杂MoS2纳米片作为高效的制氢电催化剂

为了可持续发展能量转换和存储，需要高效，稳定的用于制氢的非贵金属电催化剂。在此，开发了一种简便的低温磷化工艺，用于将磷掺杂到直接在碳布上合成的二硫化钼（MoS ₂）纳米片中，以用作有效的氢气释放反应的集成电极。与未掺杂的MoS ₂相比，最佳的磷掺杂（3.3 at％）MoS ₂纳米片表现出的较低的过电位分别为133和189 mV，以驱动20和100 mA cm ^-2的电流密度，并且其Tafel极小67.0 mV dec ^-1的斜率。在酸性介质中的出色稳定性也使掺磷的MoS ₂纳米片催化剂在实际应用中有望成为制氢的候选者。
