摘要：Multiwalled carbon nanotubes (MWNTs) as a usual supporter were directly used as a visible light photocatalyst for the degradation of methyl orange (MO) in aqueous solution. The MWNTs exhibited high photocatalytic activity for the degradation of MO under visible light irradiation. Moreover, the photocatalytic activity of MWNTs was greatly enhanced when Pt nanoparticles were loaded on the surface of MWNTs. In order to understand the photocatalytic behavior of MWNTs, the electrochemical impedance spectra and the adsorption characterization of MWNTs were investigated. On the basis of these experiments, a possible visible light photocatalytic degradation mechanism was discussed.
