چکیده مقاله:
Titania nanotubes have been synthesized as a supporter with high specific area by the hydrothermal treatment of TiO2 powders. By investigating other articles, we found that the most efficient catalayst in this process is Molybdenum with 10% wt. So to enhance the characterization of Molybdena supported on TNT, Ag as a promoter was added. An auspicious catalyst for oxidative dehydrogenation of propane (ODP) was prepared via the incipient wetness impregnation method. The as-prepared catalyst characterization was investigated using BET, SEM, EDS and XRD. Although specific surface area loss according to BET, The effect of Ag loading as a promoter in Ag/MoTNT-10 catalyst through characterization of the surface molybdena species and catalytic performance was significant.. Presence of Ag depicts that propylene yield increased from 9.3% to 11.8% as well as the growth in selectivit.
