Abstract

A novel photoelectrochemical sensor has been designed with polyaniline–reduced graphene oxide–titanium dioxide, which was further applied to sense gallic acid and exhibited extraordinary rapid response, high sensitivity and excellent anti-inference. Meanwhile, the mechanism has been elaborately explored.
