From: Substrate effect on hydrogen evolution reaction in two-dimensional Mo2C monolayers
Atomic structures of (a) Mo2C and (b) Mo2C on a metal substrate. The pink, brown, and blue balls represent Mo, C, and substrate atoms, respectively. In (a), hydrogen absorption sites are denoted by TH, TC, and TM, which are on-top of a hexagonal center, C atom, and Mo atom, respectively.
