Modelling studies for photocatalytic degradation of organic dyes using $ TiO_{2} $ nanofibers
Abstract In this work, modelling of the photocatalytic degradation of para-nitrophenol (PNP) using synthesized electrospun $ TiO_{2} $ nanofibers under UV light illumination is reported. A dynamic model was developed in order to understand the behaviour of operating parameters, i.e. light intensity...

| 520 | |a Abstract In this work, modelling of the photocatalytic degradation of para-nitrophenol (PNP) using synthesized electrospun $ TiO_{2} $ nanofibers under UV light illumination is reported. A dynamic model was developed in order to understand the behaviour of operating parameters, i.e. light intensity and catalyst loading on the photocatalytic activity. This model was simulated and analysed for both $ TiO_{2} $ solid nanofibers and $ TiO_{2} $ hollow nanofibers, applied as photocatalysts in the Langmuir–Hinshelwood kinetic framework. The entire photocatalytic degradation rate follows pseudo-first-order kinetics. The simulated results obtained from the developed model are in good agreement with the experimental results. At a catalyst loading of 1.0 mg $ mL^{−1} $, better respective degradation rates were achieved at UV light irradiance of 4 mW $ cm^{−2} $, for both the $ TiO_{2} $ solid and hollow nanofibers. However, it was also observed that $ TiO_{2} $ hollow nanofibers have a higher adsorption rate than that of $ TiO_{2} $ solid nanofibers resulting in a higher photocatalytic degradation rate of PNP. | ||

The entire photocatalytic degradation rate follows pseudo-first-order kinetics. The simulated results obtained from the developed model are in good agreement with the experimental results. At a catalyst loading of 1.0 mg $ mL^{−1} $, better respective degradation rates were achieved at UV light irradiance of 4 mW $ cm^{−2} $, for both the $ TiO_{2} $ solid and hollow nanofibers. However, it was also observed that $ TiO_{2} $ hollow nanofibers have a higher adsorption rate than that of $ TiO_{2} $ solid nanofibers resulting in a higher photocatalytic degradation rate of PNP.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Photocatalytic degradation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nanofibers</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Dynamic modelling</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Simulation</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rana, Mohit Singh</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gupta, Raju Kumar</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Environmental science and pollution research</subfield><subfield code="d">Springer Berlin Heidelberg, 1994</subfield><subfield code="g">25(2017), 21 vom: 05.

Modelling studies for photocatalytic degradation of organic dyes using $ TiO_{2} $ nanofibers |
| abstract |
Abstract In this work, modelling of the photocatalytic degradation of para-nitrophenol (PNP) using synthesized electrospun $ TiO_{2} $ nanofibers under UV light illumination is reported. A dynamic model was developed in order to understand the behaviour of operating parameters, i.e. light intensity and catalyst loading on the photocatalytic activity. This model was simulated and analysed for both $ TiO_{2} $ solid nanofibers and $ TiO_{2} $ hollow nanofibers, applied as photocatalysts in the Langmuir–Hinshelwood kinetic framework. The entire photocatalytic degradation rate follows pseudo-first-order kinetics. The simulated results obtained from the developed model are in good agreement with the experimental results. At a catalyst loading of 1.0 mg $ mL^{−1} $, better respective degradation rates were achieved at UV light irradiance of 4 mW $ cm^{−2} $, for both the $ TiO_{2} $ solid and hollow nanofibers. However, it was also observed that $ TiO_{2} $ hollow nanofibers have a higher adsorption rate than that of $ TiO_{2} $ solid nanofibers resulting in a higher photocatalytic degradation rate of PNP. © Springer-Verlag GmbH Germany 2017 |
