Summary:[Display omitted] •A kind of novel heteropolyacid-loaded catalyst POM@MOF-199@MCM-41 was synthesized.•The structure of MOF-199 with POM encapsulated in is clear under crystal analysis.•Under O2, PMM exhibits excellent catalytic performance for deep desulfurization.•The oxidation of DBT followed pseudo-first-order kinetics. A catalyst system designed by a kind of hybrid material POM@MOF-199@MCM-41 (PMM) was found by a one pot and POM template self-construction of MOF-199 in the pore of MCM-41. This catalyst was exploited to act as a stable heteropolyacid-based one in the direct oxidative desulfurization process with a feedstock of model oil under O2 as oxidant. Based on optimal conditions, the DBT conversion reached up to 98.5% and the PMM could be recycled ten times with a slight decrease, which was compared with heteropolyacid only based on MOF-199 and MCM-41, respectively. Additionally, the structure of ordered nano-sized pores of MOF-199 with POM encapsulated in was clear under crystal analysis, which offered strong evidences for the further movement into the MCM-41.
