A self-supported direct borohydride-hydrogen peroxide fuel cell system with internal manifolds and an auxiliary control unit is reported. The system, while operating under ambient conditions, delivers a peak power of 40 W with about 2 W to run the auxiliary control unit. A critical cause and effect analysis, on the data for single cells and stack, suggests the optimum concentrations of fuel and...

Ruthenium nanoparticles stabilised by polymer immobilized ionic liquids catalyse the hydrolytic release of hydrogen from sodium borohydride. The composition influences performance and ruthenium an amine-decorated imidazolium-based immobilised liquid ([email protected]2-PIILS) was most efficient with a maximum initial turnover frequency (TOF) 177 moleH2.molRu−1.min−1, obtained at 30°C catalyst l...

The 15e square-planar complexes [Co(PCPMe-iPr)Cl] (2a) and [Co(PCP-tBu)Cl] (2b), respectively, react readily with NaBH4 to afford complexes [Co(PCPMe-iPr)(η2-BH4)] (4a) and [Co(PCP-tBu)(η2-BH4)] (4b) in high yields, as confirmed by IR spectroscopy, X-ray crystallography, and elemental analysis. The borohydride ligand is symmetrically bound to the cobalt center in η2-fashion. These compounds are...

Morphologically controlled Pd-based nanocrystals are the most efficient strategies for improving electrocatalytic ethanol oxidation reaction (EOR) performance; however, their morphological-EOR activity relationship and effect of electrolytes at a wide pH range still ambiguous. Here, we have synthesized porous self-standing Pd clustered nanospheres (Pd-CNSs) nanocubes (Pd-NCBs) EOR in acidic (H2...

Reduction of oxi me fu nctionality to amine is an important synthetic transformation . As ox imes are stable derivatives of carbonyl compounds, subsequent reduction to amines is an attractive two-step procedure for reductive ami nation . Red uction of oximes to amines can be performed by hydride reducing agents or by catalytic hydrogenation.' Among hydride reducing agents, lithium aluminium hyd...
