Realizing stable transition metal(111) metallene by introducing a non-metallic framework to construct 2D Janus TMB2X (X = O and S) nanostructures and investigating their hydrogen evolution catalytic performance

The group VIII TM(111) metallene can be effectively stabilized using the nonmetallic framework of BO/BS, creating novel 2D Janus TMB 2 X (X = O and S) nanostructures. They can hold great potential for electrocatalysis in the HER reaction.
