The catalytic effect of copper in Devarda’s Al-Cu-Zn alloy (Dev. alloy) and sole metallic copper, salts oxides the coaction NaBH4 within hydrodehalogenation (HDH) polybrominated phenols, such as herbicide Bromoxynil alkaline aqueous solution has been investigated. Namely, hydrodebromination (HDB) activity Dev. alloy/NaOH system compared to heterogeneous Cu-based catalysts using a reductant. Dif...

We report on the enhancement of the electrocatalytic activity of Au nanoparticles after NaBH4 treatment and its application to H2O2 detection.

Paraquat [(2 MP*), 1,l '-dimethyl-4,4'-bipyridine dication] is a herbicide used for weed control in various crops or for desiccation of marihuana plants. Accidental and suicidal poisonings with paraquat are not uncommon (1). Several analytical methods have been published for the determination of 2 MP' in human body fluids, postmortem tissues, air, and foods consumed by humans. Analysis of 2 MP'...

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 ...

Currently, the Brown-Schlesinger process is still regarded as the most common and mature method for the commercial production of sodium borohydride (NaBH4). However, the metallic sodium, currently produced from the electrolysis of molten NaCl that is mass-produced by evaporation of seawater or brine, is probably the most costly raw material. Recently, several reports have demonstrated the feasi...

The early reported pseudo-first-order reaction kinetics of the polymer-supported metallic nanocatalysts for the model reaction of p-nitrophenol (p-NP)/NaBH4 were probably oversimplified. Here a detailed study of p-NP reduction by NaBH4 in the presence of the raspberry-like poly(allylamine hydrochloride)-modified polymer poly(glycidyl methacrylate) composite sub-microspheres with tunable gold na...

A series of monometallic borohydrides and borohydride eutectic mixtures have been investigated during thermal ramping by mass spectroscopy, differential scanning calorimetry, and photography. Mixtures of LiBH4-NaBH4, LiBH4-KBH4, LiBH4-Mg(BH4)2, LiBH4-Ca(BH4)2, LiBH4-Mn(BH4)2, NaBH4-KBH4, and LiBH4-NaBH4-KBH4 all displayed melting behaviour below that of the monometallic phases (up to 167 °C low...
