Enhanced photocatalytic activity of titanium dioxide by nut shell carbon

Nut shell carbon (NSC)–nanotitanium dioxide (TiO 2) composites were prepared by sol–gel method. Photocatalytic activity on degradation of dye Rhodamine B was studied. X-ray diffraction, field emission scanning electron microscopy, Brunauer–Emmett–Teller surface area, pore size distribution, ultravio...

Description
Summary:Nut shell carbon (NSC)–nanotitanium dioxide (TiO 2) composites were prepared by sol–gel method. Photocatalytic activity on degradation of dye Rhodamine B was studied. X-ray diffraction, field emission scanning electron microscopy, Brunauer–Emmett–Teller surface area, pore size distribution, ultraviolet–vis light absorption spectrum, and photoluminescence spectrum were carried out to characterize the composite catalyst. The results indicated that the photocatalytic activity of NSC–nano-TiO 2 composites was much higher than P25 (Degussa). NSC could greatly absorb the organic substance and oxygen of solution because of its large surface area.
