In this work,acid functionalized multi-wall carbon nanotubes(MWCNTs) were modified with imidazolium-based ionic liquids.The selective oxidation of various alcohols with hydrogen peroxide catalyzed by [PZnMo_2W_9O_(39)]~(5-),ZnPOM,supported on ionic liquids-modified with MWCNTs,MWCNTAPIB,is reported.This catalyst[ZnPOM@APIB-MWCNT],was characterized by X-ray diffraction,scanning electron microscopy(SEM) and FT-IR spectroscopic methods.This heterogeneous catalyst exhibited high stability and reusability in the oxidation reaction without loss of its catalytic performance.
