Ever since the discovery of the pH-sensing properties of ZnO crystals, researchers have been exploring their potential in electrochemical applications. The recent expansion and availability of chemical modification methods has made it possible to generate a new class of electrochemically active ZnO nanorods. This reduction in size of ZnO (to a nanocrystalline form) using new growth techniques i...

The zinc-cadmium oxide (ZnO-CdO) nanocomposites with different weight percentages of cadmium oxide (CdO) nanoparticles were successfully synthesized by the sonochemical method using zinc and cadmium nitrates as precursors to probe their nano-structured surfaces for the decomposition reactions of chloroethyl phenyl sulfide (CEPS) as a surrogate of sulfur mustard agent simulant. Scanning electron...

A facile precipitation method has been developed to synthesize ZnO with [bis(2-aminoethyl)amino]methyl lignin (lignin amine) that is chemically modified from low-cost pulp industrial lignin. The obtained ZnO crystallites have been characterized to exhibit a hexagonal wurtzite structure, and their sizes have been determined at ca. 24 nm (mean value). These ZnO nanocrystallites are of high purity...

Room-temperature large-scale highly ordered nanorod-patterned ZnO films directly integrated on III-nitride light-emitting diodes (LEDs) are proposed and demonstrated via low-cost modified nanoimprinting, avoiding a high-temperature process. with a 600 nm pitch on top of a critical 200 nm thick Imprinting ZnO nanorods of 200 nm in diameter and 200 nm in height continuous ZnO wetting layer, the l...

Glassy carbon electrode (GCE) was modified with metal oxides (MO = Fe3O4, ZnO) nanoparticles doped phthalocyanine (Pc) and functionalized MWCNTs, and the electrocatalytic properties were studied. Successful synthesis of the metal oxide nanoparticles and the MO/Pc/MWCNT composite were confirmed using FTIR, Raman and SEM techniques. The electrodes were characterized using cyclic voltammetry (CV) ...

Nanoparticles of zinc oxide (ZnO) were prepared by the precipitation method from zinc sulphate (ZnSO4.7H2O) and sodium bicarbonate (NaHCO3). Organization, stabilization of the ZnO nanoparticles from further growth and partially inhibiting the photodegradation was achieved by capping with poly vinyl pyrrolidone (PVP). Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD)...

Anisotropic yolk/shell or Janus inorganic/polystyrene nanocomposites were prepared by combining miniemulsion polymerization and sol-gel reaction. The morphologies of the anisotropic composites were found to be greatly influenced by surface modification of zinc oxide (ZnO) nanoparticle seeds. Two different types of the oleic acid modified ZnO nanoparticles (OA-ZnO) were prepared by post-treatmen...

In the present paper, a gamma alumina (?-Al2O3) loaded zinc oxide (ZnO) nano-catalyst (ZnO/?-Al2O3) has been synthesized and used to accelerate removal of sulfur compounds from light gas oil by oxidative desulfurization (ODS) process. The nano-catalysts have characterized atomic force microscopy (AFM) Brunauer-Emmett-Teller (BET). ODS process conducted in batch reactor at various reaction tempe...

With increasing production and applications of nanostructured zinc oxide, e.g., for biomedical and consumer products, the question of safety is getting more and more important. Different morphologies of zinc oxide structures have been synthesized and accordingly investigated. In this study, we have particularly focused on nano-micro ZnO tetrapods (ZnO-T), because their large scale fabrication h...
