Enhanced xylene removal by photocatalytic oxidation using fiber-illuminated honeycomb reactor at ppb level.

Highlights: [•] The combination of optical fiber and honeycomb significantly enhanced the performance of VOCs photodegradation. [•] The removal efficiency of m-xylene is enhanced to 96.5% as compared to 22.0% for UV irradiation alone. [•] Fiber-illuminated honeycomb reactor is the first step toward an industrial-scale technology on the removal of xylene. [Copyright &y& Elsevier]
