Abstract
In this paper, a novel mesoporous sulfated zirconium (M-ZrO2/SO42−) has been gotten by one-pot evaporation-induced self-assembly (one-pot EISA) strategy. The SXRD, N2-physisorption and TEM characterization techniques indicated that M-ZrO2/SO42− possessed distinct mesostructure with big specific surface area (133.5m2g−1), large pore volume (0.18cm3g−1) and narrow pore size distribution (4.90nm). Moreover, the existing states and the influence in mesostructure of introduced S species were detailedly investigated by the XRD, N2-physisorption, TEM, TG-DSC, FT-IR and XPS techniques and the results showed that the S species, which existed as the type of SO42−, improved the textural properties of prepared materials. In addition, the NH3-TPD and IR spectra of adsorbed pyridine indicated the existence of strong Brønsted and Lewis acid sites in M-ZrO2/SO42− even evacuated at 400°C. Furthermore, the M-ZrO2/SO42− was used as a promise solid acid catalyst and displayed excellent catalytic performance and reusability in Friedel-Crafts benzylation reaction.
