Hydrogen production through water splitting has been considered as a green, pure
and high-efficient technique. As an important half-reaction involved, hydrogen
evolution reaction is a complex electrochemical process involving
liquid-solid-gas three-phase interface behaviour. Therefore, new concepts and
strategies of material design are needed to smooth each pivotal step. Here we
report a multiscale structural and electronic control of molybdenum disulfide
foam to synergistically promote the hydrogen evolution process. The optimized
three-dimensional molybdenum disulfide foam with uniform mesopores, vertically
aligned two-dimensional layers and cobalt atoms doping demonstrated a high
hydrogen evolution activity and stability. In addition, density functional theory
calculations indicate that molybdenum disulfide with moderate cobalt doping
content possesses the optimal activity. This study demonstrates the validity of
multiscale control in molybdenum disulfide via overall consideration of the mass
transport, and the accessibility, quantity and capability of active sites towards
electrocatalytic hydrogen evolution, which may also be extended to other
energy-related processes.
