AbstractThe difficulties in designing high-performance hydrogen evolution reaction (HER) catalysts lie in the manipulation of adsorption behaviors of transition metals (TMs). Topological chiral semimetals with super-long Fermi arc surface states provide an ideal platform for engineering the catalytic performance of TMs through the metal-support interaction. We found the adsorption trends of TMs can be modified significantly when deposited at the surface of the PdGa chiral crystal. The electron transfer from the TMs to the surface states of the PdGa reshapes the d band structure of TMs and weakens the hydrogen intermediate bonding. Especially, W/PdGa is expected to be a good HER catalyst with close to zero Gibbs free energy. Experimentally, we found a Pt-like exchange current density and turnover frequency when depositing W atoms at the PdGa nanostructures surface. The findings provide a way to develop high-efficient electrocatalysts by the interplay between topological surface states and metal-support interaction.
