Synthesis of N, P dual‐doped MoS2 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 (MoS2) 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 MoS2 on hollow carbon spheres (denoted as P‐MoS2@NCs) has been developed via template sacrifice, polymerization, and hydrothermal process. The synergistic effect between the N, P dual‐doped hollow carbon spheres, and MoS2, which has abundant active sites can enhance the electrocatalytic performance of HER. As expected, the formed P‐MoS2@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 H2SO4. It provides a new method to develop advanced MoS2‐based catalyst for the HER. [ABSTRACT FROM AUTHOR]
