Abstract

Methylidyne, vinylidene and ethylidyne on a surface: Inelastic neutron scattering (INS) vibrational spectroscopy is used to investigate the surface intermediate species formed during the decomposition of methane on Ru/Al2O3 and Ni/SiO2 catalysts. The findings are compared to previous work on idealized single-crystal model catalysts and begin to bridge the gap between surface science and real-world catalysts in terms of the type of material and pressure used.
