AI Technical Summary
Traditional COD detection technologies are time-consuming, use expensive and toxic reagents, generate secondary toxic waste, have poor reproducibility, and rely on biological enzymes, making them susceptible to external factors that can lead to inaccurate results.
Using fluorine-doped tin oxide (FTO) conductive glass as a substrate, TiO2 nanorods are grown via hydrothermal method and coated with perfluorosulfonic acid (Nafion) to form a TiO2/Nafion composite photoelectrode, avoiding the use of biological enzymes and improving stability and sensitivity.
It enables rapid, simple, and environmentally friendly detection of organic matter in water, and is particularly sensitive to low concentrations of glucose. It is highly stable, easy to operate, and highly adaptable, avoiding the use of biological enzymes.
