Abstract

Well-defined Co_xCeO_2+x–MoS₂ nanotube hybrids were first obtained by a facile solvothermal method. The Ce_0.3Co_0.7O_x–MoS₂ nanohybrids exhibited superior performance for the hydrogen evolution reaction due to synergistic effects between Co_xCeO_2+x and MoS₂, which significantly reduced the charge-transfer impedance and increased the active sites.
