2017) Preparation and characterisation of Preyssler heteropolyacid-cellulose acetate hybrid nanofibers: a new, green and recyclable nanocatalyst for photodegradation of methyl orange as the model dyeABSTRACT For the first time, sodium 30-tungstopentaphosphate, a green and efficient solid acid, was used for the isolation of cellulose from rice husk, resulting in the generation of Preyssler heteropolyacidcellulose acetate hybrid nanofibers. These modified fibres were characterised by Fourier

It was also showed that Preyssler heteropolyacid was evenly dispersed on or into the nanofibers and the distribution became denser as the concentration of Preyssler HPA increased. The electrospuned nanofibers were employed successfully for the photodegradation of methyl orange, a common azo dye pollutant in the environment.
