Abstract

A photo-electrode of hydrogenated TiO2 nanorod arrays (H-TNRs) was prepared and used as a photoelectrochemical sensor for organic compound detections for the first time. Under visible light, the H-TNR electrode has shown a highly sensitive and steady photocurrent response due to introduction of oxygen vacancy and mid-gap energy levels. The H-TNRs are a promising material for photoelectrochemical detection of organic compounds under visible light.
