Compounds containing both ketone and amide carbonyl groups were reduced with sodium borohydride (NaBH4). In this way, secondary alcohols, which are very important compounds for the synthesis of drugs, agricultural chemicals, food other obtained regioselectivity. To do this, starting compound 2-(5-amino-1,3,4-thiadiazol-2-yl)thio)-1-(3,4-dichlorophenyl)ethanone (3) was obtained. Subsequently, 10...

In this study, carbon nanotube supported Pd catalysts (Pd/CNT) are synthesized at different weight percentages by the sodium borohydride (NaBH4) reduction method to investigate catalytic performance of glucose electrooxidation reaction. 0.5% Pd/CNT, 3% and 7% Pd/CNT characterized using X-ray diffraction (XRD), electron microscopy with energy dispersive (SEM-EDX), N2 adsorption-desorption measur...

Development of in-born porous nature of zirconium hydroxide nanopowders through a facile hydrogen (H2) gas-bubbles assisted borohydride synthesis route using sodium borohydride (NaBH4) and novel information on the temperature-mediated phase transformation, pore geometry as well as pore hysteresis transformation of in-born porous zirconium hydroxide nanopowders with the help of X-ray diffraction...

An improvement in the previously reported seed-mediated chemical synthesis of gold nanorods (GNRs) is reported. Monodisperse GNRs have been synthesized in a one-step protocol. The addition of controlled quantity of sodium borohydride (NaBH4) directly into the growth solution produced uniform GNRs, formed by in situ nucleation and growth. In order to arrive at the conclusion, we studied the form...

The need for an alternative energy source that is both clean and abundant has led to research into a hydrogen economy. Hydrogen gas can be produced slowly via the hydrolysis of sodium borohydride (NaBH4). A catalyst used speed up rate at which produced, however many catalysts involve relatively expensive materials like precious metals. This study explores novel copper nanoparticle supported on ...

This study presents the use of modified coffee husk and lignin as sorbents in heavy metal ions sorption Pb(II), Cd(II), Cr(III), Cu(II) an aqueous solution. The modification was carried out by impregnation method, using silver nitrate (AgNO3) sodium borohydride (NaBH4) a nanoparticles’ (NPs) precursor, reducing agent, respectively. obtained nanocomposite material morphologically characterized e...

Water-soluble fluorescent Ag nanoclusters (NCs) were synthesized at room temperature with sodium dodecyl sulfonate (SDS) as a protective agent. The effects of synthetic conditions on the fluorescence properties of Ag NCs were investigated. The results show that the fluorescence intensity of Ag NCs strongly depends on the synthetic conditions, such as the molar ratio of AgNO3 versus SDS and sodi...

The electrochemical oxidation behaviors of NaBH4 on Zn, Zn–MH, and MH (metal-hydride) electrodes were investigated, and an intrinsic direct orohydride fuel cell (DBFC)/battery hybrid power source using MH (or Zn–MH) as the anode and MnO2 as the cathode was tested. Borohydride annot be effectively oxidized on Zn electrodes at the Zn oxidation potential because of the poor electrocatalytic abilit...

iron oxide (fe2o3) nanoparticles were synthesized by a simple approach using sodium borohydride (nabh4) and iron chloride hexahydrate (fecl3.6h2o). their physicochemical properties were characterized by high resolution transmission electron microscopy (hrtem), scanning electron microscopy (sem), x-ray diffraction (xrd) and electron dispersive spectroscopy (eds). xrd pattern showed that the iron...
