Enhancing ethylbenzene vapors degradation in a hybrid system based on photocatalytic oxidation UV/TiO2-In and a biofiltration process

► The best photocatalytic system for EB degradation was based on TiO2-In 1%/365 nm. ► A maximum EC of 290 g m−3 h−1 for the hybrid system was obtained. ► The hybrid process enhanced 40% the overall EC of ethylbenzene. ► An overall mineralization of 67% for EB degradation was reached in the hybrid system.
