摘要：
Porous MnCeOx solid solutions nanorods (PN-MnCeOx) with different pore sizes were prepared using different carbon chain lengths ionic liquids (C(10)mimCl, C(12)mimCl and C(14)mimCl). Series of novel catalysts with nano-Au supported on the PN-MnCeOx, were synthesized and applied to oxidative esterification of aldehydes (benzaldehyde derivatives or methacrolein - MAL) to esters. Catalytic performance was evaluated in batch reactor and the relatively optimum catalyst was screened out. Kinds of characterization methods, such as XRD, TEM, XPS and BET, were applied to analyze crystal plane, microstructure, specific surface area, and porous structure of the catalysts and the structure-activity relationship could be reasonably explained. The cyclic stability of the catalyst was also tested more than 7 times using MAL and methanol for methyl methacrylate synthesis via one step oxidative esterification.
