Research Progress in the Application of Transition Metal Oxides in Photoelectrochemical Sensors

In recent years, photoelectrochemical sensors have become a hot research. To be the key of photoelectrochemical sensor, photosensitive materials play a decisive role in the sensitivity, selectivity and stability of the sensors. In this paper, the principle and classification of photoelectrochemical sensors were briefly introduced. The preparation methods and applications of photoelectric materials commonly used in photoelectrochemical sensors for transition metal oxides and their complexes were described. The development prospects of photoelectrochemical sensors and photoelectrochemical materials were also prospected (67 ref. cited).
