WebMay 29, 2024 · In this paper, by using density functional theory methods, we investigated NH 3 decomposition reaction on three types of core−shell nanoparticles M@Ni (M = Fe, Ru, Ir) with 13 core M atoms and 42 shell Ni atoms. The size of these three particles is about 1 nm. WebThe thermodynamic potential of the 2H + /H 2 couple is plotted vs. pH (dotted line) for a comparison. At pH 6 ( Figure 9 B) and 8 ( Figure 9 C), similar behaviour can be observed. At pH 6, the Ox state is converted to Red and RedH with a higher apparent midpoint potential (−300 mV) than at pH 7 (−350 mV).
