The catalysts were characterized by N2 adsorption-desorption, XRD, SEM, TEM, XPS, FT-IR and ICP-AES analysis techniques. It was found that, through simply tuning the initial molar ratios of Zr/Si, both the morphology and catalytic performance of resultant catalysts can be tailored. More interestingly, the incorporation of zirconium ions, which can endow the ordered framework with enhanced acidity, can effectively stabilize loaded pentaethylenehexamine (PEHA) and facilitate a higher dispersion and attraction of HPW clusters. By carefully screening the catalytic results of the selective oxidation of benzyl alcohol, an optimal value of Zr/Si molar ratio was found to be 0.05, under which platelet ZrSBA-15 with ordered framework can be facilely obtained, leading to a maximum catalytic activity with negligible loss in selectivity and conversion even after five times of recycling test.
