Green Synthesis of Surfactant Capped CTAB@Ag Nanoparticles and Study of Its Catalytic Activity

In the present study, ginger extract, which is widely available as a medicinal herb, is used to develop a facile method for green synthesis of bare Ag and surfactant capped CTAB@Ag nanoparticles via Hydrothermal route. The as-prepared Ag nanoparticles were characterized by UV-Vis spectroscopy, photoluminescence (PL), X-ray Diffraction (XRD), Infrared spectroscopy (IR), and Scanning electron microscopy (SEM). The catalytic properties of as prepared bare and surfactant capped CTAB@Ag nanoparticles were also investigated in reductive degradation of Methyl Orange (MO) dye and 4-Nitrophenol (4-NP). Surfactant-capped CTAB@Ag nanoparticles exhibit superior catalytic properties in the degradation of MO and conversion of 4-nitro phenol to 4-amino phenol when compared to bare silver nanoparticles.

Effect of calcination temperature on the morphology and catalytic properties of ZnO nanostructures fabricated from a chiral precursor for photodegradation of both cationic and anionic dyes

Diverse ZnO nanostructures (ZnO_1 to ZnO_3) were synthesized by direct calcination of a chiral MOF precursor {[Zn4(µ3-OH)2(D-2,4-cbs)2(H2O)4].5H2O}n (Zn-CBS) at three different temperatures 600, 700 and 800 oC, respectively. On the...

Two Novel Telluroniobates with an Efficient Catalytic Activity for the Imidation/Amidation Reaction

We present the synthesis and catalytic properties of two novel telluroniobates {Te15Nb21} and {Te10Nb14}. {Te15Nb21} is the first trimeric telluroniobate with the largest number of tellurium atoms in Te-Nb system....

Effect of CeO2 morphology on the catalytic properties of Au/CeO2 for base-free glucose oxidation

Catalytic selective oxidation of glucose into value-added gluconic acid is one of the sustainable routes for biomass utilization, for which the supported Au catalysts have been widely explored. Au/CeO2 was...
