Photocatalytic Reactions of Titanium Dioxide for Active Packaging Application
The adsorption and photocatalytic reactions of ethylene and oxygen were investigated by sol-gel routed TiO2 particles.The dependence of ethylene-free oxygen concentrations,oxygen-free ethylene concentrations and the molar ratio of C2H4:O2 in the gas mixture on adsorption and photocatalytic reaction rates were examined.The increase of ethylene-free oxygen concentrations or oxygen-free ethylene concentrations can enhance the adsorption rates while decreasing photoreaction rates.The presence of ethylene and oxygen can increase adsorption rates leading to enhance photocatalytic rates.The photocatalytic rates of ethylene oxidation and oxygen reduction were 10-8 mol.s-1.g-1 evenly at C2H4:O2 molar ratio equal to 3:1.
