The N vs. Z plot illustrates the qualitative difference in the fis- sion behaviour of the alkaline earth metals as compared to sodium. 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.
