英文摘要The surface carbonaceous species on Mo/HZSM-5, which are formed from methane dehydrogenation and aromatization, are characterized by temperature programmed oxidation (TPO), C-13 CPMAS NMR and studied by temperature programmed surface hydrogenation reaction (TPSHR). According to their peak temperatures in the profile of TPO, three carbonaceous species of C-alpha, C-beta, and C-gamma on Mo/HZSM-5 can be detected. C-alpha is the most active and C-beta second as far as the reaction with hydrogen is concerned. C-gamma is inert and deposited on HZSM-5. Two types of surface carbonaceous species of C-sigma and C-pi on used Mo/HZSM-5 can be identified by C-13 CPMAS-NMR, whereas only C-sigma on HZSM-5. C-sigma is sp(3) coordinated carbon and C-pi is sp(2) coordinated.
