The efficiency of photoelectrochemical degradation for organic and natural pollutants relies upon not merely on the selection of a suitable supporting electrolyte and pH values, and also within the electrode prospective and preparation problems with the semiconductors concerned. Inside a photoelectrochemical system, photoelectrons and photoholes can be divided underneath the influence of an utilized electrical field.
