Constructing ternary polyaniline-graphene-TiO2 hybrids with enhanced photoelectrochemical performance in photo-generated cathodic protection

Ternary polyaniline-graphene-TiO2 nanocomposites were constructed through a stepwise synthetic route. The hybrids exhibit remarkable enhancement in photoelectrochemical performance. The transfer of photo-excited carriers in the ternary composites facilitates the photo-induced electron-hole separation. Meanwhile, the flat band potential shift of the hybrids increases the inner electric field intensity that drives the photo-excited electron...
