Photocatalysts doped with polyaniline and functionalized CNTs onto TiO2 were developed.
The PANi/CNT/TiO2 photocatalysts possessed both advantages of PANi and CNTs.
The fabricated PANi/CNT/TiO2 photocatalysts exhibited high photocatalytic activity under sunlight.
The hydrothermal synthesized PANi/CNT/TiO2 presented a good photocatalytic activity and the sol–gel ones presented a good photocatalytic stability.
