The Cu(II) complexes were synthesized via re...

Copper oxide (CuxO) photocathode has received an enormous amount of attention for photoelectrochemical (PEC) green fuel generation, such as hydrogen, methane, ethane, methanol, and ethanol. Although CuxO is highly photoactive, it is limited by the mismatched charge diffusional length and light a...

In the current decade, the development of recyclable, renewable, and sustainable products to replace fossil products is an essential and important matter for industrial and environmental purposes. In the present study copper (II) oxide nanoparticles were dispersed in SAE10W-30 to reduce wear and...

In this study, we developed a facile approach for synthesizing CuO nanostructures and their conversion into stable nanostructured Cu via a green method. The release of hydroxyl radicals by the phytochemicals present in Psidium guajava leaves was exploited in the synthesis process. The structural...

Arsenic (As) in rice grains is a serious food safety concern. Some coexisting engineered nanoparticles (ENPs) were shown to alter the accumulation and speciation of As in rice grains. However, investigation on the effects of copper oxide nanoparticles (CuO NPs), a popular ingredient in pesticide...

Oxidation of saturated hydrocarbon by transition metal complexes is of great importance because this would give industrially valuable organic fine chemicals. Here, dinuclear copper(II) and dinuclear nickel(II) complexes with same N,O donor ligand have been used as catalyst for the oxidation of c...

The process of oxidative dehydrogenation of the pentadentate amine ligand 2,10-bis-(2′-pyridyl)-3,6,9-triazaundecane (L1am) mediated by Cu(II) in the absence of an external oxidant led to the Cu(I) mono-imine complex, [CuIL1im](BPh4). This complex was quite sensitive towards air oxidation, lead...

Copper(II) oxide powder manufacture from H2O2 type etching waste is proposed. The basic copper carbonate, the intermediate product, is depends on the reaction mole ratio of sodium carbonate to copper hydroxide. The optimum reaction mole ratio is 2.64 at 80℃ under copper content of 57.5 wt.%.The...

Nanobiocatalysis is the combination of the unique properties of nano-sized materials and the efficiency and sophistication of catalytic properties of enzymes.
