Abstract
A recyclable catalyst of sliver nanoparticles well dispersed in mesoporous silica was successfully synthesized via a straight-forward strategy combining electrospinning technique with post-calcination. The resulted mats containing silver nanoparticles of 10±4 nm size well dispersed in mesoporous silica fibers of 380±80 nm diameter presented surface plasma resonance of silver nanoparticles at 420 nm. The catalytic behavior of the nanofiber on the reduction of methylene blue by NaBH4 was tracked and showed that the silver nanoparticles immobilized on silica nanofibers matrix possessed excellent catalytic properties, which may hold great promise in effective and eco-friendly waste water treatment.
