In this study we report synthesis of TiO2/CNTs composite by simple grinding method and study improving their photocatalytic activity under visible light. The photocatalytic activities of samples were assessed by photodegradation of methylene blue (MB). | Home Search Collections Journals About Contact us My IOPscience A study on carbon nanotube titanium dioxide hybrids experiment and calculation This content has been downloaded from IOPscience.

The structure of TiO2 CNT hybrid samples was determined by x-ray diffractometer D5005 Siemen with CuKα radiation. Their morphology and sizes were investigated with FE-SEM and HR-TEM which shows that nanoparticles were coated on CNTs. The UV vis absorption results indicate interaction between TiO2 and CNTs the composite material can absorb at higher wavelength and the
