Adsorption and reduction of NO on tin(IV) oxide doped with chromium(III) oxide

Elementary steps of the catalytic NO(x) reduction with NH3: cluster studies on reactant adsorption at vanadium oxide substrate.

Extended cluster models together with density-functional theory are used to evaluate geometric, energetic, and electronic properties of different adsorbate species that can occur at a vanadium oxide surface where the selective catalytic reduction (SCR) of NO in the presence of ammonia proceeds. Here, we focus on atomic hydrogen, nitrogen, and oxygen, as well as molecular NO and NHx, x = 1, 4, a...

Surface Adsorption of Polyethylene Glycol and Polyvinyl Alcohol with Variable Molecular Weights on Zinc Oxide Nanoparticles

Synthesis and Characterization of the Ti-Doped Vanadium Oxide Nanotubes

Synthesis of different kinds of nanotubes were considering after the discovery of carbon nanotubes . Lately has been noticed synthesis of vanadium oxide nanotubes. Vanadium oxide nanotubes are made of multilayer scrolls with thick walls built up from several vanadium oxide layers. This compunds be used as catalysts, molecular sieves, absorbents and energy storage devices. In this research study...

Adsorption Mechanism of Lead on Wood/Nano-Manganese Oxide Composite

Discharge of untreated industrial wastewater containing heavy metals such as Pb2+ is hazardous to the environment due to their high toxicity. This study reports on the adsorption, desorption, and kinetic study on Pb2+ removal from aqueous solutions using wood/Nano-manganese oxide composite (WB-NMO). The optimum pH, contact time and temperature for adsorption were found...
