Two-dimensional amorphous MoSx (a-MoSx) has been confirmed to be a highly active and economic electrocatalyst for hydrogen evolution reaction (HER). The development of its hybrid cocatalyst is envisioned to bestow more active sites with appropriate crystal engineering and modified electronic properties for enhancing catalytic performance. In this work, a composite cocatalyst comprising a-MoSx (x = 1.78) and well-ordered anodized TiO2 nanotube arrays (TNAs) is successfully developed through a facile electrodeposition route. The synergistic coupling of the unique vector charge transfer effect of TNAs and proliferation of active sites in a-MoSx derived from the space confinement effect and curv..View full abstract
