Mesoporous TS-1: Nanocasting synthesis with CMK-3 as template and its performance in catalytic oxidation of aromatic thiophene

Mesoporous TS-1, with additional mesopore system formed by packing the TS-1 nanocrystals, was synthesized by nanocasting route using nanoporous carbon (CMK-3) as template and characterized by XRD, BET, TEM, UV–vis and FT-IR. Catalytic performance of mesoporous TS-1 in H2O2 oxidation of aromatic thiophene, the model sulfur containing molecule in transportation fuels, was tested and reported. Compared with common TS-1, mesoporous TS-1 shows improved catalytic performance for thiophene oxidation and is able to catalyze oxidation of bulky sulfur containing molecule such as dimethyldibenzothiophene.
