Zinc in: Polyoxometalate 1 reacts with Zn2+ ions in acetone to form a novel sandwich‐type POM 2 in almost quantitative yield. The H2O2‐based oxidation of secondary alcohols with 2 efficiently proceeds, with an activity and chemoselectivity that is very different from those of tungsten‐based catalysts including 1 (see scheme; green Zn).
Methanol partial oxidation on Cu–Zn thin films epitaxially grown on Ni(100) surface has been investigated in an ultra high vacuum (UHV) system combined with a high-pressure reaction cell. According to temperature programmed reaction (TPR) and temperature programmed desorption (TPD) in UHV, surface reaction between methanol and pre-adsorbed oxygen on epitaxially grown Cu thin films mainly produced...
At oxidizing of liquid zinc by H2O/CO2 mixture at supercritical parameters it is found the formation of nanoparticles (ZnO)n with size from 1.5 to 100 nm and combustible substances: H2, CO, lower paraffin and aromatic hydrocarbons, alcohols and formaldehyde. Composition of combustible products depends on H2O/CO2 ratio in mixture. Synthesized ZnO samples were studied by methods of scanning and transmission...
