Highly organized arrays of TiO2nanotubes (as depicted in the figure) are integrated into a thin-cell photoelectrocatalytic reactor for the rapid determination of chemical oxygen demand in wastewater samples. The high photocatalytic activity of the nanotubes arises from the efficient separation of photogenerated electrons and holes, and enables the fabrication of sensors exhibiting good accuracy, stability, and reproducibility.
