The incorporation of P into Pt–Co nanoalloys is used to regulate the electron density around Pt for high-efficiency methanol electrooxidation.

Fourteen yeast strains from six genera were analysed for the presence of long-chain alcohols. Six strains from three genera contained long-chain alcohols, highest levels being found in Candida afbicans. The alcohols were identified and determined by TLC, GLC and GLC-MS. The major long-chain alcohols synthesized by these organisms were saturated, primary alcohols with C1 4, C I 6 or C18 chain le...

ALCOHOLS  The lower aliphatic alcohols are low to moderately toxic and usually have low vapor pressures, therefore inhalation toxicity is low.  Vapors may be an irritant to the eyes and mucous membranes.  Ingestion and absorption of the liquids through the skin can be a major health hazard.  Lower alcohols containing double or triple bonds exhibit a greater degree of toxicity and irritation...

Solvothermaly synthesized zirconium oxide nanopowders, pure and doped with various amounts of iron ions (1?20 %), were used as modifiers glassy carbon electrodes. The modified electrodes tested in the reaction electrochemical oxidation 2,4,6-trichlorophenol (TCP) order to investigate influence doping on performance zirconia matrix. techniques cyclic voltammetry impedance spectroscopy employed. ...

Unsubstituted phthalocyanines of Co, Fe and Mn supported on zinc oxide nanoparticles were prepared and were well characterized with X-ray diffraction and scanning electron microscopy. The oxidation of alcohols with tert-butylhydroperoxide, in the presence of metallophthalocyanines supported on zinc oxide nanoparticles was investigated. These MPc/ZnO nanocomposites were effective catalysts for t...

A convenient approach for oxidation of structurally diverse alcohols has been developed using KMnO4 as oxidant agent in the presence of a catalytic amount of Al2O3 in aqueous acetonitrile. In this method various alcohols generally afforded the corresponding carbonyl compounds directly in good to high yield under ultrasound irradiation conditions. It shows that this kind of catalysis system is v...

The electrooxidation of PFOS can be significantly improved with the simultaneous electrosynthesis ferrate and permanganate from low concentration ambient Fe 2+ Mn in source waters, even presence natural organic matter (NOM).
