A facile green method was proposed for synthesis ofthree dimensional Ag-nanoparticledecorated mesoporous nanofiber membrane. The proposed method avoides the use of high temperture thermal treatment as well as hazardous solvents, which is a typical environmental friendly apprach. Sol-gel and electrospinning methods was applied for the fabrication of the membrane followed by template extraction and Ag-nanoparticle decoration. The characterization results revealed that the prepared membrane has a mesoporous structure with a surface area and pore size of 406 m2 g-1 and 3.51 nm, respectively. In addition, the Ag-nanoparticles with a diameter 5 to 10 nm were grown in a well coordination and distribution along the nanofibrous. The membrane displayed highly efficient antibacterial  performance in dark, a complete Esherichia Coli inactivation was achieved within 30 minutes. The membrane recovery and reuse was convenient due to the 1D properity of the fiber. The strategy to immobilize AgNPs within a mesoporous nanofibers can be extended to other particle systems for various applications in catalysis, energy, sensing, photonic and biomedical applications.
