“…Because trifluoroethylene is copolymerized with acrylate monomers, the polyacrylate portion of PZ-0 is random polymer, so the peak strength is weak. According to the diffraction standard, all samples except PZ-0 showed diffraction peaks in 2θ = 31.88°, 34.42°, 36.38°, 47.64°, 56.72°, 62.86° and 67.96°, corresponding to (100), ( 002), ( 101), ( 102), ( 110), ( 103), ( 200), ( 112), ( 201), ( 004) and (202) planes, that consistent with the hexagonal wurtzite ZnO (JCPDS card No 80-0074) [27]. Furthermore, a characteristic peak of PCTFEco-acrylate at 20.25° was found in all samples except ZnO, demonstrating that ZnO was well embedded in the polymer matrix.…”

With the continuous growth of industrialization, residual dyes degradation has been a hotspot in present research. Herein, the immobilization of ZnO into polychlorotrifluoroethylene-coacrylate (PCTFE-co-acrylate) matrix render hybrid film with good hydrophilicity and ageing resistance. We studied the effects of different ZnO/PCTFE-co-acrylate ratio on photocatalytic behavior under ultraviolet illumination. The best degradation ability of methylene blue (MB) was obtained for PZ-1 owe to Zn 2+ and defect levels, which achieved up to 96.3% at 120 min later. Meanwhile, concerned kinetics property was adequately explored, which match well with pseudofirst order reaction. Such a simple, green and convenient approach provides a high-performance hybrid film for dyes wastewater purification.

In this study, aqueous Cystoseira crinite extract was used to successfully biosynthesize ZnO and C-doped ZnO samples. X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray (EDX), FTIR, and UV–vis techniques were used to characterize the biosynthesized samples. XRD technique confirmed the crystalline structure of ZnO and C-doped ZnO. EDX confirmed the formation of C-doped ZnO. SEM analysis revealed the spherical shape of the samples with agglomeration. FTIR spectra showed that phenolic compounds and protein molecules are present in the Cystoseira crinite extract. The photocatalytic activity of the prepared photocatalysts was investigated using crystal violet (CV) as a model of the cationic dyes and methyl orange (MO) as a model of the anionic dyes. 5%C-doped ZnO calcined at 500 °C showed an optimum photocatalytic efficiency of 92.7% and 87.8% for CV and MO dyes, respectively. The improved photocatalytic activity could be attributed to the narrower optical band gap of C doped ZnO than pure ZnO. The photocatalytic activity of CV and MO dyes follows the first-order kinetics with high correlation coefficient values. Graphical Abstract
