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 (MoS 2 ) nanosheets directly synthesized on carbon cloths to function as an integrated electrode for efficient hydrogen evolution reaction. The optimal phosphorus‐doped (3.3 at%) MoS 2 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 MoS 2 , and an impressively small Tafel slope of 67.0 mV dec −1 . The excellent stability in acid media also makes the phosphorus‐doped MoS 2 nanosheet catalysts promising candidates for hydrogen generation in practical applications.
