Process of using a catalyst for photo-catalytic degradation of contaminant in water

A process, comprising:

• fitting a cooling jacket;
• adding a Pd/Ce2O3—ZnO photo-catalyst into deionized water containing MTBE and forming a solution;
• loading the solution onto a photochemical reactor and stirring continuously;
• collecting a sample from de-ionized water containing MTBE and designating as an initial concentration of MTBE (Co);
• saturating the sample by passing oxygen;
• collecting the next sample from de-ionized water containing MTBE;
• exposing the sample to UV light;
• collecting the sample at a regular interval of time and estimating an amount of MTBE in collected samples using a gas chromatography.
