Multi-walled carbon nanotubes (MWCNTs), titanium(IV) isopropoxide (TIP) and potassium hexachloroplatinate(IV) (K2PtCl6) were used for the preparation of Pt/MWCNT/TiO2 composites. The composites were comprehensively characterized by Brauer-Emett-Teller surface area, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, energy dispersive X-ray and UV-vis absorption spectroscopy. The photoactivity of the prepared materials under UV irradiation was tested using the conversion of methylene blue (MB) in aqueous solution. According to the results ofMBremoval experiment, it can be considered that the MB removal effect of the Pt/MWCNT/TiO2 composites is affected by two kinds of effects: adsorption effect by MWCNTs and photocatalytic effect by TiO2. Finally, the photocatalytic effect increases due to photo-induced-electron absorption effect by MWCNTs and electron trap effect by Pt metal.
