Innovative metal boride nanocatalysts containing crystalline Co–Ni based binary/ternary phases were synthesized and used in the hydrolysis of NaBH4. All as-prepared catalysts high-purity with average particle sizes ranging between ~51 94 nm consisting different (e.g. CoB, Co2B, Co5B16, NiB, Ni4B3, Ni2Co0·67B0.33). The synergetic effect composite had a positive role on catalytic performances thu...

Chlorinated organic solvents (COSs) are a significant threat to human beings. In this study, nanoscale bimetallic Ni/Fe particles were synthesized from the reaction of sodium borohydride (NaBH4) with reduction Ni2+ and Fe2+ in an aqueous solution. The zero-valent iron (nZVI) Ni-nZVI characterized by SEM (scanning electron microscopy), XRD (X-ray diffractometer), Brunauer–Emmett–Teller (BET), tr...

The effect of concentration of reduction agent of sodium borohydrate (NaBH4) on the properties of silicon nanoparticles synthesized via microemulsion route is reported. In this work, the concentration of the silicon tetrachloride (SiCl4) that served as silicon source with sodium hydroxide (NaOH) and polyethylene glycol (PEG) as stabilizer and surfactant, respectively, are keep fixed. Four sampl...

The physical properties and the hydrogen release of NaBH4–Mg(BH4)2 and NaBH4−Ca(BH4)2 composites are investigated using in situ synchrotron radiation powder X-ray diffraction, thermal analysis and temperature programmed photographic analysis. The composite, xNaBH4–(1 − x)Mg(BH4)2, x = 0.4 to 0.5, shows melting/frothing between 205 and 220 °C. However, the sample does not become a transparent mo...

Borohydride salts have been considered as good prospects for transportable hydrogen storage materials, with molecular hydrogen released via hydrolysis. We examine details of the hydration of sodium borohydride by the combination of X-ray absorption spectroscopy and first principles' theory. Compared to solid sodium borohydride, the aqueous sample exhibits an uncharacteristically narrow absorpti...

VOCs, volatile organic compounds, which are mostly produced by the excessive emission of different industrial and commercial activities, pose a serious hazard to human health primarily contribute creation photochemical smog, has significant influence on air quality. The treatment VOCs catalytic oxidation at lowest feasible temperature been acknowledged as an efficient cost-effective approach. H...

A variety of phosphine oxides and sulfides can be efficiently converted directly to the corresponding phosphine boranes using oxalyl chloride followed by sodium borohydride. Optically active P-stereogenic phosphine oxides can be converted stereospecifically to phosphine boranes with inversion of configuration by treatment with Meerwein's salt followed by sodium borohydride.

Silver nanoparticles (Ag-NPs) have gained immense attention among the variety of metallic during past decades. In addition to distinctive optical and electrical properties, Ag-NPs been particularly employed for their biocidal features in industrial products, especially biomedicine. Despite wide range studies applications Ag-NPs, yet serious limitations remained unsolved such as environmental to...

well faceted cuo nanoparticles, were synthesized by thermal-assisted dissociation method at reflux temperature in a short period of time. a possible mechanism for synthesis of such highly pure and stable nanoparticles is tentatively proposed by ft-ir study. the large surface area and rich exposed active sites are expected to endow such nanoparticles with excellent performances in catalysis as d...
