Hydrothermal synthesis of single-walled carbon nanotube-TiO2 hybrid and its photocatalytic activity

► SWCNT-TiO2 was hydrothermally prepared via direct growth of TiO2 on SWCNTs. ► Well-dispersed SWCNTs inhibit growth of TiO2 and improve its thermal stability. ► The photoactivity of TiO2 was enhanced significantly with SWCNT introduction.
