This work presents results on the dissociation of H 2 S over Ni–Mo catalysts suggesting that the presence of surface Mo-atom(s) has a significant impact on both the energetics of the process and the reaction mechanism. The presence of one Mo atom p

In production of synthesis gas (syngas) from natural gas, carbon deposition is the major cause of catalyst deactivation, specifically on Ni-based catalysts. Because the rate of carbon formation is greater than the rate of carbon gasification, carbon
