Ethylene is an ideal CO2 product in electrocatalytic reduction reaction (CO2RR) with high economic value. This paper synthesised Al-doped octahedral Cu2O (Al–Cu2O) nanocrystal by a simple wet chemical method. The selectivity of CO2RR products was improved doping Al onto the surface Cu2O. Al–Cu2O used as efficient electrocatalyst for selective ethylene production. exhibited % Faradic efficiency ...

Atomic layer deposition (ALD) of alumina using trimethylaluminum (TMA) has technological importance in microelectronics. This process has demonstrated a high potential in applications of protective coatings on Cu surfaces for control of diffusion of Cu in Cu2S films in photovoltaic devices and sintering of Cu-based nanoparticles in liquid phase hydrogenation reactions. With this motivation in m...

Hollow metal oxide nanocrystals were prepared by etching cuprous oxide with metal ions and were applied as photoelectrodes. As a hard template, polyvinylpyrrolidone stabilized cuprous oxide (PVP-Cu2O) and non-stabilized cuprous oxide (nPVP-Cu2O) were synthesized by a precipitation method. Hollow iron oxide and cobalt oxide nanocrystals with a truncated octahedral morphology were fabricated by a...

Several studies have shown that combining TiO2 and Cu2O enhances the photocatalytic activity of material by generating a heterojunction capable extending light absorption in visible reducing electron-hole recombination rate. Ball milling has been chosen as an alternative methodology for photocatalyst preparation, among several techniques documented literature review. The results previously repo...

Along with industrialization and rapid urbanization, environmental remediation is globally a perpetual concept to deliver sustainable environment. Various organic inorganic wastes from industries domestic homes are released into water systems. These carry contaminants detrimental effects on the Consequently, there an urgent need for appropriate wastewater treatment technology effective decontam...

Cu seed layers for future interconnects must have conformal step coverage, smooth surface morphology, and strong adhesion. Conformal deposition had been achieved by chemical vapor deposition CVD , but CVD Cu films have rough surfaces and poor adhesion. In this paper, conformal, smooth, adherent, continuous, and thin 9 nm Cu films were made by CVD. CuON was deposited from a Cu-amidinate precurso...

This work reports on the concurrent electrochemical energy storage and conversion characteristics of granular copper oxide electrode films prepared using reactive radio-frequency magnetron sputtering at room temperature under different oxygen environments. The obtained films are characterized in terms of their structural, morphological, and compositional properties. X-ray diffraction, X-ray pho...

Copper has many applications, particularly in electro-catalysis, where the oxidation state of the copper electrode plays a significant role in the selectivity towards products. Although copper-based materials have clear potential as catalysts in the reduction of CO2 and conversion to products, fundamental understanding of CO2 adsorption and activation on different copper oxide surfaces is still...

Conductive polypyrrole–polyaniline/TiO2 nanocomposites (PPy–PANI/TiO2) were prepared by in situ oxidative copolymerization of pyrrole and aniline monomers in the presence of TiO2. For comparison studies, polypyrrole/TiO2 (PPy/TiO2) and polyaniline/TiO2 (PANI/TiO2) were also prepared. The samples were characterized by X-ray diffraction, transmission electron microscopy, UV-vis diffuse reflectanc...
