Hollow polydopamine spheres decorated with MoS <sub>2</sub> nanosheets for the hydrogen evolution reaction
Hollow carbon spheres decorated with MoS<sub>2</sub> (HCS@MoS<sub>2</sub>) were synthesized using SiO<sub>2</sub> templating and polydopamine carbonization. The porous carbon shell enlarges the electrochemically active surface area, while flower-like mixed-phase MoS<sub>2</sub> nanosheets expose catalytic sites. The ecofriendly electrocatalyst exhibits a low HER overpotential (0.3 V at 10 mA cm<sup>-2</sup>) and remarkable stability.
