限域于SBA-15孔道内过渡金属硫化物活性相定向调控方法研究

In this paper, the contruction of active phase of transition metal sulfides confined within the channel of SBA-15 was performed by the thermal decomposition of the transition metal salt of the active components to elucidate the structure-activity between the active phase morphology and the catalytic performance. The HRTEM analysis results showed that the distributions of MoS2 particles over the SBA support were more uniform, and the slab lengths was 5 nm and the predominant slabs was 4~5. The evaluation results of the catalytic performance in hydrodesulfurization (HDS) of dibenzothiophene (DBT) indicated that the MoS/SBA catalyst showed higher HDS activity than that of the MoS/Al2O3 catalyst.
