Ag-functionalized Bi2W(Mo)O6/PVDF membrane for photocatalytic water treatment
Costly and time-consuming recovery of photocatalysts from treated water is one of the main challenges for the photocatalysis process. In this regard, an Ag-functionalized Bi2W(Mo)O6 photocatalyst was successfully synthesized via a cetyltrimethylammonium bromide (CTAB)-assisted hydrothermal method, immobilized on a polyvinylidene fluoride (PVDF) membrane and subsequently used for photocatalytic water treatment. The flower-like Ag-decorated Bi2W(Mo)O6 photocatalyst revealed a significant enhancement (62%) in the photocatalytic degradation efficiency compared to the unmodified pure Bi2WO6 (19%) due to the synergic contribution of the flower-like morphology with higher surface area, decrease in band gap by Mo doping and Ag-induced surface plasmon resonance (SPR) effects. In order to immobilize the photocatalyst, the Ag-decorated Bi2W(Mo)O6 nanoparticles were distributed uniformly on the surface of the PVDF membrane. The results illustrate that the as-prepared Ag-loaded Bi2W(Mo)O6/PVDF composite membrane effectively degrades the organic molecules (51%) without any additional process for the photocatalyst separation, confirming its potential as a beneficial environmental-friendly material for water treatment applications.
期刊介绍：
The Journal of Materials Science publishes reviews, full-length papers, and short Communications recording original research results on, or techniques for studying the relationship between structure, properties, and uses of materials. The subjects are seen from international and interdisciplinary perspectives covering areas including metals, ceramics, glasses, polymers, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials.
