| description | <p dir="ltr">Cobalt (Co) co-doped TiO<sub>2</sub> photo-catalysis were synthesized, characterized and tested toward solar photocatalytic oxidation of toluene (TOL). A multi-technique approach was used to characterize and relate the photo-catalytic property to photo-oxidation performance. Adding Co to TiO<sub>2</sub> significantly changed crystal size and surface morphology (surface area, pore-volume, and pore size), reduced the bandgap energy of TiO<sub>2</sub> and improved the solar photo-oxidation of TOL. Up to 96.5% of TOL conversion (% TN<sub>conv</sub>) was achieved by using CoeTiO<sub>2</sub> compared with 28.5% with naked TiO<sub>2</sub>. The maximum %TN<sub>conv</sub> was achieved at high hydraulic retention time (HRT) 100 s, Co content in the photo-catalyst of 5 wt% and relative humidity (%RH) of 50%. The mechanism of TOL solar oxidation was related to the concentration of OH and O<sup>-</sup> <sub>2</sub> radicals produced from the generated electrons and holes on the surface of Co eTiO<sub>2</sub>. The products formed during the photo-catalytic oxidation of TOL were mainly CO<sub>2</sub> and water, and minor concentration of benzene and benzaldehyde. Overall, the CoeTiO<sub>2</sub> could be used as a potential photo-catalyst for the oxidation of toluene in gas-phase streams on an industrial scale.</p><h2>Other Information</h2><p dir="ltr">Published in: Chemosphere<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.chemosphere.2020.126878" target="_blank">https://dx.doi.org/10.1016/j.chemosphere.2020.126878</a></p> |
