Synthesis of N, P dual‐doped MoS 2 on hollow carbon spheres for hydrogen evolution reaction

Summary Developing cheap and abundant materials as high efficient HER catalysts to replace noble metal catalysts is urgent. Molybdenum disulfide (MoS 2 ) as one attention‐drawing material still has an enormous limit due to the layers stacking and the lacking of active sites. Therefore, the N, P dual‐doped MoS 2 on hollow carbon spheres (denoted as P‐MoS 2 @NCs) has been developed via template sacrifice, polymerization, and hydrothermal process. The synergistic effect between the N, P dual‐doped hollow carbon spheres, and MoS 2 , which has abundant active sites can enhance the electrocatalytic performance of HER. As expected, the formed P‐MoS 2 @NCs‐2 exhibits excellent electrochemical property for HER. The overpotential at 10 mA cm −2 and Tafel slope are as low as 147 mV (V vs RHE) and 72 mV/dec. Otherwise, it shows excellent durability in 0.5 M H 2 SO 4 . It provides a new method to develop advanced MoS 2 ‐based catalyst for the HER.
