Abstract
The mechanism of methane dissociation on an Rh-decorated Ni(100) surface has been investigated Using density functional theory. The study includes the determination of the most stable adsorbate/adsorbent configurations of the species associated with subsequent reactions and generating the energy surface for 𝐶𝐻4 dissociation process. The Rhdecorated Ni(100) surface was found to be more favorable for the process than the NiRh(111) configuration, mainly due to lower the activation energy of 𝐶𝐻 decomposition reaction by 48.5%, leading to a higher conversion of 𝐶𝐻4 to carbon and hydrogen
