Electrodeposition of polyaniline onto TiO2 nanoparticles/multiwalled carbon nanotubes for visible light photoelectrocatalysis.
In this study, polyaniline (PANI) was coated onto TiO2 nanoparticles/multiwalled carbon nanotubes (TiO2/MWCNTs) hybrid by electrochemical polymerization. Modification of TiO2/MWCNTs with PANI endows the resulted hybrid with visible light activity. The PANI/TiO2/MWCNTs hybrid shows remarkable photoelectrocatalytic activity for the degradation of RhB under visible light irradiation. The enhanced photocatalytic activity of the PANI/TiO2/MWCNTs hybrid originates from the effective charge transfer properties of the heterojunctions of PANI-TiO2 and TiO2-MWCNTs. The efficient charge transportation and high photoelectrocatalytic activity towards degradation of rhodamine B make this novel hybrid material promising for photocatalysis and for the development of photoelectrical devices.
