In order to assess the potential for using copper oxide as the oxygen source in chemical looping combustion with coal, a study was undertaken to characterize the reaction rates of copper oxide with carbon monoxide, a major coal partial oxidation product. In the study, CO oxidation experiments ...
carbon dioxide hydrogenation indicates that, along with the wurtzite zinc oxide phase, around 16 mol% of zinc is present in a reduced form as copper–zinc bulk alloy, and around 2 mol% as surface zinc formate (Fig.2b). Cu K-edge XANES and EXAFS (Supplementary Figs.7–10, ...
such catalysts require the precise control of tin loading amount. Here, we develop a copper/tin-oxide catalyst with dominant tin oxide surface being formed via a spontaneous exchange reaction between sputtered tin and copper oxide. Even though...
Copper Oxide for CO2Reduction Reactions Copper (Cu) based catalysts are the most suitable agent for CO2RR, especially for assembling multi-carbon-containing substances (Petersonet al., 2010). Cu stands out from other metals due to its low hydrogen underpotential deposition, which prevents the hydro...
We delineate the excellent bactericidal efficacy of stable heterojunction nanocomposites composed of single-walled carbon nanotubes (SWCNTs) and copper(II) oxide (CuO) synthesized via facile recrystallization and calcination. The bactericidal effectiveness of the fabricated nanocomposites was examined using the...
This highly efficient transformation is realized through the use of copper(I) iodide as a catalyst, N,N'-dimethylethylenediamine as a ligand, and Cs2CO3 as a base. A variety of sterically hindered and/or functionalized substrates were found to react under these reaction conditions to provide ...
The selective electroreduction of carbon dioxide to C2 compounds (ethylene and ethanol) on copper(I) oxide films has been investigated at various electrochemical potentials. Aqueous 0.1 M KHCO3 was used as electrolyte. A remarkable finding is that the faradic yields of ethylene and ethanol can be ...
The most important compounds are the oxide and the sulfate, blue vitriol; the latter has wide use as an agricultural poison and as an algicide in water purification. Copper compounds such as Fehling’s solution are widely used in analytical chemistry in tests for sugar. High-purity copper (...

In addition, cyclic imines are present in the substructures of various bioactive secondary metabolites; e.g., gymnodimine (antagonist for nicotinic acetylcholine receptors)20,21, koranimine (antibiotic)22, and venoms of fire ants (inhibitors of nitric oxide synthase)23. Synthetic cyclic imine sugars...
