Hydrogen evolution electrocatalysts in high-fold degenerate topological semimetals with chiral structures

Topological catalysts are special class of high-activity catalysts that have topological surface state with high-mobility electrons to promote electron transfer. Among topological materials, high-fold degenerate topological semimetals (TSMs) with chiral structures are particularly effective in hydrogen evolution reaction (HER) catalysis due to the larger energy window of nontrivial surface states and longer Fermi arcs than other classes. In this work, based on high-throughput calculations and th
