WebApr 12, 2024 · Density functional theory (DFT) calculations indicate that the adsorption and dissociation of CH 4 and the formation of lattice hydroxyls with the lattice oxygen adjacent to Pt 1 are the key reasons for the formation of a Pt 1 –OV combination. WebThe differential charge density indicates a significant electron redistribution behavior of R-CoC 2 O 4 @MXene in a heterogeneous structure, which optimizes the adsorption energy of the reaction intermediates, thus delivering an excellent HER activity (η 1000 = 216 mV) (Figure 7c). Transition metal-based phosphides often have good HER activity.
