Single-atomic rhenium-assisted 2H-to-1T phase transformation of MoS2 nanosheets boosting electrocatalytic hydrogen evolution

Single-atomic Re on 1T-2H MoS 2 heterostructure demonstrates HER performance on par with Pt/C electrocatalyst. This good performance is attributed to the introduction of Re single atoms that promote phase transition and serve as active sites for water dissociation.
