Preparation and Photocatalytic Properties of Silver Doped Titanium Dioxide Nanoparticles and Using Artificial Neural Network For Modeling of Photocatalytic Activity

This paper presents a study on the preparation method for Ag-TiO2 nano particles. Photodeposition of silver on TiO2 nanoparticles was carried out by adding a desired volume of aqueous AgNO3. Ag-deposited TiO2 catalyst was characterised by XRD, TEM, SEM. The Ag-TiO2 catalyst was evaluated for their photocatalytic activity towards the degradation of Malachite green (MG) under UV irradiation. An artificial neural networks (ANN) model was developed to predict the performance of degradation efficiency by Ag-TiO2/UV process based on experimental data obtained in a laboratory batch reactor. A comparison between the predicted results of the designed ANN model and experimental data was also conducted. The model can describe the color removal percent under different conditions.
