| 英文摘要 | Phosphotungstic acid (H3PW12O40) has been successfully loaded onto amino-functionalized ionic liquid modified mesoporous silica SBA-15 by totally anion-exchange and partly protonating in the channel of SBA-15 with Keggin-type H3PW12O40. XRD patterns, N-2 adsorption-desorption isotherms and TEM images confirm the intact mesostructures of the samples. Thermal analysis, Si-29 MAS NMR and P-31 MAS NMR indicate the presence of the [PW12O40](3-) (PW) in the mesopores. FT-IR spectra suggest that a portion of free amino groups in the amino-functionalized IL moiety are remained in the channel of the catalysts, although there are ionic interactions between PW anions and protonated amino groups, as well as between PW anions and imidazolium cations. Hydrophilic amino-functionalized IL moiety in the mesostructures, especially, the remained free amino groups flexibly anchored on the imidazolium, plays a crucial role in enhancing the accessibility of H2O2, which in turns significantly improves the catalytic performance. The resultant PW loaded on amino-functionalized IL modified SBA-15 (PW-NH2-IL-SBA-15) catalysts are proven to be versatile in the solvent-free oxidation of alcohols with aqueous 30% H2O2, presenting high efficiency, convenient recovery and steady reuse.
