Abstract

3D MoS₂ hollow spheres were successfully fabricated by hydrothermal process. Commercial bulk MoS₂ had quite large grain size and preferential (002) grain orientation, while as-prepared MoS₂ hollow spheres had refined grain and random grain orientation. Meanwhile, the hydrogen evolution reaction of the commercial bulk MoS₂ and as-prepared MoS₂ hollow spheres was systematically investigated in acidic solution. The as-prepared MoS₂ hollow spheres catalyst exhibited a lower onset overpotential for hydrogen evolution reaction than bulk MoS₂. The superior hydrogen evolution reaction activity could be attributed to the unique 3D MoS₂ hollow spheres which provided more active edge sites. In addition, 3D MoS₂ hollow spheres also exhibited excellent high chemical stability after 1000 potential cycles.
