In　this　study,　a　novel　electrospun　nanofibrous　composite　was　synthesized　from　polyacrylonitrile　(PAN)　and　well-dispersed　oxide　nanoparticles　containing　Ti　and　Ag　(PAN-TA).　The　nanoparticles　incorporated　into　the　nanofibers　can　endow　the　composite　with　photocatalytic　and　antimicrobial　ability.　The　morphologies　and　structure　of　the　nanofibers　were　characterized　by　Fourier　transform　infrared　(FTIR),　scanning　electron　microscopy　(SEM)　and　X-ray　diffraction　(XRD).　Controlled　experiments　were　carried　out　with　the　effects　of　chemical　modification,　solution　pH,　temperature,　dosage,　contact　time,　and　initial　concentration　of　the　dye.　The　methylene　blue　(MB)　dye　was　completely　removed　within　20　min　at　room　temperature　25　oC　with　high　maximum　retention　capacity　of　155.4　mg　g-1.　Moreover,　equilibrium　data　and　kinetics　data　indicated　that　the　dye　adsorption　agreed　well　with　the　Langmuir　isotherm　model　and　pseudo-second　order　model,　respectively.　In　addition,　the　nanofibers　could　be　easily　separated　from　dye　solution　and　showed　high　reusability　for　numerous　repeat　cycles,　thus　indicating　good　application　prospects　for　the　wastewater　treatment.　©　2018　Sociedade　Brasileira　de　Química.
