Silver nanoparticle embedded polymethacrylic acid/ polyvinylpyrrolidone nanofibers for catalytic application
A facile way to fabricate the highly uniform and mono-disperse silver nanoparticles (AgNPs) immobilized in polymer nanofibers has been successfully developed by combining electrospinning technique and photo-reduction method, applicable as efficient catalysts. Herein, poly-vinyl pyrrolidone (PVP) for...

description | A facile way to fabricate the highly uniform and mono-disperse silver nanoparticles (AgNPs) immobilized in polymer nanofibers has been successfully developed by combining electrospinning technique and photo-reduction method, applicable as efficient catalysts. Herein, poly-vinyl pyrrolidone (PVP) forbids the silver grain growth due to its steric effect and polymethacrylic acid (PMAA) contributes abundant carboxylic groups, which enhances the absorption of silver ions in nanofibers ensuring the growth of high density of AgNPs. UV exposure of nanofibers for 24 h leads to the maximum density of growth of AgNPs in PMAA/PVP nanofibers. The present investigation indicates that the size and spatial distribution of AgNPs can be tailored by changing the concentration of AgNO3 solution consequently, controlling the catalytic activity of AgNPs-immobilized nanofibrous mats. Interestingly, the prepared nanofibers exhibit good catalytic activity towards the reduction of methylene blue an environmental organic pollutant, due to the high density of AgNPs formation in nanofibers.
