The increasing knowledge in nanoscience and materials technology promoted the development of advanced with enhanced unusual properties suitable for sustainable applications ranging from energy to environmental purposes. Here are presented some results our current investigations on composite semiconducting materials. investigated composites have been prepared different nitrogen precursors thin f...

2D photoactive materials may offer interesting opportunities in photocatalytic devices since they combine strong light absorption and shortening of charge carriers’ diffusion path. Because their high surface defect concentration the formation a majority edge/plane vs plane/plane contacts between anisotropic building blocks, passivation improvement carrier transport are critical for large develo...

ABSTRACT Water pollution by organic pollutants is a continuous and increasing problem of global concern. In this paper, we developed nanocrystalline cellulose (NCC) titania (TiO2) based nanocomposite for the photocatalytic degradation o-chloranil via aqueous wet impregnation. Different NCC loadings (10, 20, 40, 80%) were used, several analytical microscopy techniques characterised NCC/TiO2 cata...

In this study, Zinc oxide nanoparticles were synthesized by gel-combustion method using a novel bio-fuel tapioca starch pearls, derived from the tubers of Mannihot esculenta, to investigate the photocatalytic degradation of ccaffeine. The ZnO photocatalyst was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-visible spectroscopy. X-ray diffractometry result f...

At the first stage Fe3O4 and Fe nanoparticles were synthesized via a simple hydrothermal method. Then silver nanoparticles and Fe-Ag nanocomposites were synthesized in the presence of NaBH4. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy, and Fourier transform infrared spectroscopy. Vibrating Sample magnetometer illustrated that Fe nanopartic...

Biosynthesis of metal nanoparticles using plant extract has received much attention due to its eco-friendly nature. The present study elucidates the green synthesize of Silver nanoparticles (AgNPs) from methanolic extract of Coleus Vettiveroids –an endemic species. The synthesis of AgNPs was confirmed by UV-visible spectrometry at 416 nm. Further, biosynthesized nanoparticles were characterized...
