High-performance hydrogen evolution reaction in quadratic nodal line semimetal NaCdSn.

Topological nodal line semimetals (TNLSMs), which exhibit one-dimensional (1D) band crossing in their electronic band structure, have been predicted to be potential catalysts in electrocatalytic processes. However, the current studies are limited to the TNLSMs where the dispersion around the nodal line is linear in all directions. Here, the potential application of the quadratic nodal line (QNL) semimetal NaCdSn in hydrogen evolution reaction is explored.

This investigation provides a comprehensive exploration into the intricate interplay between topological surface states (TSS) and catalytic performance in two-dimensional (2D) materials, with specific emphasis on monolayer CuSe.

Our findings illuminate the central role played by these TSS, arising from the underlying NLSM framework, in sculpting catalytic efficiency.

Drumhead surface states promoted hydrogen evolution reactions in type-II nodal-line topological catalyst MgBi.

An excellent catalyst generally meets three indicators: high electron mobility, high surface density of states and low Gibbs free energy (Δ) [H. Luo , 2022, , 611-624]. Recent studies have confirmed that topological materials exhibit more advantages than conventional precious metals with regard to the above-mentioned indicators.
