WebbThe ionic liquid-templated TON- and MFI-type zeolites having 10-membered rings were synthesized and their catalytic performances on propene dimerization were studied. The comparable acid site strength among TON- or MFI-type zeolites accounted for the nearly identical propene dimerization turnover rates despite their different Si/Al ratios.
