| Abstract: | Carbon nanotubes(CNT) were modified by cetyltrimethylammonium bromide(CTAB) and so-dium dodecyl sulfate(SDS),and used to prepare catalyst TiO2/CNT.The catalytic activity of TiO2/CNT was tested by the transesterification between phenol and dimethyl carbonate(DMC).The catalysts were charac-terized by X-ray diffraction,SEM and TEM.The results showed crystalline TiO2 were not yet formed,while amorphous was favorable to the transesterification.ICP results approved that more active species were loaded on CNT modi... |
