•Desilication of TS-1 gives rise to hierarchical materials with bimodal PSD.•Desilicated TS-1 exhibits a large BET surface area and well-developed mesoporosity.•Desilicated TS-1 remains the activity of the original TS-1 for small molecules.•Desilicated TS-1 shows an improvement for the oxidation of bulky molecules.
A series of modified TS-1 samples have been produced by desilication of the original TS-1 (4 wt.% Ti) using a chemical treatment with NaOH. Desilicated TS-1 zeolites exhibit a large BET surface area together with a well-developed mesoporosity. The hierarchical catalysts from desilication of TS-1 zeolite show a good catalytic activity for the oxidation of small molecules and a significantly higher activity for the oxidation of bulky molecules.
