Green-Routed Carbon Dot-Adorned Silver Nanoparticles for the Catalytic Degradation of Organic Dyes

γ-CD-Functionalized TiO2 Nanoparticles For the Photocatalytic Degradation of Organic Dyes

In this work, an efficient photocatalyst based on gamma-cyclodextrin-modified titanium dioxide nanoparticles (TiO2/γ-CD NPs) was synthesized and used for photocatalytic degradation of rhodamine B (RhB), methyl orange (MO) and methylene blue (MB). The results of FESEM, EDX, TEM, FT-IR, XRD and BET surface area measurement showed that the TiO2 NPs were effectively modifi...

Photocatalytic degradation of some organic dyes under solar light irradiation using TiO2 and ZnO nanoparticles

Nanoparticles of the ZnO and TiO2 were synthesized and the physicochemical properties of the compounds were characterized by IR, X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The XRD patterns of the ZnO and TiO2 nanoparticles could be indexed to hexagonal and rutile phase, respectively. Aggregated nanoparticles of Z...

Biosynthesis of Ag Nanoparticles at Ziziphus Jujuba Kernel Substrate using Tilia platyphyllos Extract: Catalytic Activity for Reduction of Organic Dyes

For the first time the extract of the plant of Tilia platyphyllos was used to green synthesis of Ag nanoparticles (NPs) supported on Ziziphus jujuba kernel as an environmentally benign support. Ag NPs/ Ziziphus  jujuba  kernelas  an  effective  catalyst  was  prepared  through reduction  of Ag+ions using Tilia  platyphyllos extractas  the  reducing  and capping agent  and Ag  NPs immobilization...

Synthesis of silver nanoparticles using bacterial exopolysaccharide and its application for degradation of azo-dyes

In this study, the synthesis and characterization of exopolysaccharide-stabilized sliver nanoparticles (AgNPs) was carried out for the degradation of industrial textile dyes. Characterization of AgNPs was done using surface plasmon spectra using UV-Vis spectroscopy, X-ray diffraction (XRD) and Raman spectroscopy. The morphological nature of AgNPs was determined through transmission electron mic...
