Preparation and application of TiO2-graphene-polyaniline non-enzyme sensor

The invention belongs to the field of electrochemical sensors, and particularly relates to a preparation method based on a TiO2-graphene-polyaniline (TiO2-RGO-PANI) non-enzyme sensor. The invention provides a preparation method of a TiO2-graphene-polyaniline non-enzyme sensor for the backwardness of sensor materials and technology. The method adopts one-pot method to prepare the composite material; synchronously compares the performance study of TiO2, RGO, and PANI composite materials on a non-enzymatic glucose sensor; and determines that the TiO2-RGO-PANI composite material has a good detection effect on the non-enzymatic glucose sensor. The method further compares the electrochemical behavior of the glucose on the modified electrode, and the result of the electrochemical test shows thatas the scanning speed increases, the oxidation peak current also increases correspondingly, and the effect of the TiO2-RGO-PANI composite material on the glucose is irreversible. In the range of different urea concentrations,
