Role of oxygen transfer and surface reaction in catalytic performance of VO -Ce1–Zr O2 for propane dehydrogenation

Nano-Hierarchical SSZ-13-Supported Low-Polymerized VOX as Highly Efficient Catalysts for Propane Dehydrogenation

“…As shown in Figure S3a, both SSZ-13 and V 2 O 5 showed relatively low catalytic activity, with about 10% propane conversion and 30% propylene selectivity. After loading VO X species on the SSZ-13 zeolites, all the obtained x V/SSZ catalysts show high propylene selectivity and (>70%) and stability (Figure ), indicating high C–H bond activation ability of VO X species. − The fraction of exposed VO X species first increases with the increasing V loading from 1 to 5 wt % and then decreases with further incremental V loading to 12 wt % owing to the gradual formation of crystalline V 2 O 5 . Thus, both propane conversion and propylene selectivity follow a volcano trend as a function of V loading and reach the maximum values for 5V/SSZ.…”

Revealing the mechanism of VOx/Ti3AlC2 for the dehydrogenation of propane

“…8,9 The oxidative dehydrogenation of propane (ODHP) is an alternative approach to PDH, but the overoxidation reaction results in a lower propene yield and hinders its industrial application. 10–13 Therefore, to overcome these shortcomings, both PDH and ODHP reactions urgently need to be developed using more appropriate catalytic systems.…”
