Fotoelectrocatalytic Degradation of Organic Compound Congo Red Using TiO2/Ti Electrode

Abstract

In this study, we synthesized photobilized TiO₂ on a Ti plate and tested its photoelectrocatalytic activity towards Congo Red. The background of this research is to develop an effective and environmentally friendly water treatment method. The main method used was the sol-gel synthesis of TiO₂ prepared from titanium tetra isopropoxide as a complexing agent, followed by photobilization on a Ti plate. Material characterization was conducted using XRD technique, portable Potentiostat (e-DAQ), and UV-Vis DRS (Diffuse Reflectance Spectrophotometric) spectroscopy. The results of this research showed that the TiO₂ synthesis produced Anatase crystal structure with particle size of 13–16 nm and a band gap of 3.20 eV. Furthermore, the photoelectrocatalysis test demonstrated that TiO₂/Ti exhibited activity in degrading Congo Red. The main conclusion of this study is that the synthesis of TiO₂/Ti using the Sol-Gel method and immobilization on a Ti plate can enhance the photodegradation efficiency towards Congo Red. This finding has significant implications in the development of more effective and environmentally friendly water treatment technologies.
