Fabrication of a photo-catalytic cell using polymer-based composite films and investigation of its performance in the degradation of methyl blue

Abstract

A photo-catalytic cell was fabricated using CdS/polymer composite films with a CdS particle layer on the surface. The cell exhibited high efficiency in the photo-degradation of methyl blue.

Facile Fabrication of Porous ZnS and ZnO Films by Coaxial Electrospinning for Highly Efficient Photodegradation of Organic Dyes

“…The ZnS/SF composite displays no obvious light absorbance in the region of 200–800 nm. The absorbance of the ZnS/C mats at around 295–330 nm belongs to ZnS nanoparticles which correspond with our previous report . A significant absorption band at 369 nm was detected in the curve of ZnO porous films, which is the characteristic absorbance of wurtzite hexagonal phase .…”

Coaxial Electrospinning Method for the Preparation of TiO2@CdS/PVA Composite Nanofiber Mat and Investigation on its Photodegradation Catalysis

“…Compared to the curve representing pure PVA, peaks of TiO 2 appeared at 2 θ values of about 39.8, 44.8 and 64.8°, corresponding to the hkl (004) , (111) and (105) of TiO 2 appeared in the two composite nanofibers’ curves. In the TiO 2 ‐SiO 2 @CdS/PVA curve, two new peaks at a 2 θ of 23.2 and 28.9° appeared, these peaks could be attributed to CdS .…”

“…To prepare the composite films, polymers were often chosen as the supporting materials to anchor nanoparticles. In our previous work, the as‐prepared CdS/polymer composite materials could effectively catalyze dye degradation, the degradation efficiency reaching 77% within 150 min .…”

The molecular structure control of butyl methacrylate/acrylamide (co)polymers

“…Seven symmetrical chemical shifts centered 39.5 ppm may be ascribed to DMSO [28]. Levy et al [29], Kumar et al [30] and Yiru Jia et al [31] reported the 13 C NMR analyses of the homopolymer and copolymer of BMA. Therefore, the chemical shift at 177.5 ppm may be ascribed to ester carbonyl carbon C e (C_O) of BAM.…”
