The loading of phosphotungstic acid on UiO-66 support improved the catalytic performance for oil desulfurization, especially when defects were present.
Phosphotungstic acid (H3PW12O40, HPW) exhibits a good desulfurization performance towards the oxidative desulfurization (ODS) of oil-derived fuels. However, it presents two drawbacks: a small specific surface area and poor recovery. In this work, HPW was loaded on the support UiO-66 with a stable structure and large specific surface area, and a family of HPW@UiO-66 catalysts was prepared. Based on the structure and property analyses of powder FT-IR, ICP-OES, XRD, SEM, TG and BET, 0.5-HPW@UiO-66 with defects possessed a high crystallinity, regular morphology, stable structure and dispersed HPW clusters. The removal efficiency of DBT reached 100% and was maintained at 94.70% after 12 times of repeated use under the optimal reaction conditions. The results showed that the catalytic performance of HPW@UiO-66 catalyst for model oil desulfurization was improved when the defects existed.
