Photoelectrochemical water splitting is a promising solution for harnessing solar radiation for hydrogen production. Copper oxide semiconductors, particularly materials based on cuprous oxide, have attracted attention due to their abundant elemental availability and scalable synthesis methods. To improve the gen...
The direct-grown p-type copper oxide nanowires on copper foil were fabricated via a facile and cost-effective template route for photoelectrochemical (PEC) hydrogen generation. The dense and curl-shaped copper oxide nanowires were carried out through thermal transformation of one-dimensional Cu(OH)(...

Pure liquid copper in a moist, oxidizing environment, causes water molecules to break down on its surface, releasing hydrogen to diffuse away rapidly into its interior. This behavior is common to many liquid metals. The oxygen released in the same reaction (Equation 1.2), and copper oxide, Cu2...
Before the bonding experiments, wet etching was performed to remove organic contaminants and the oxide layer. The test dies were rinsed with deionized water, followed by a short immersion in a mixed solution of citric acid and deionized water (in the ratio 133 g/100 ml) at 25 °C ...
A proof-of-principle double-layer symmetrical supercapacitor with nanoporous copper/copper oxide electrodes and an aqueous electrolyte is investigated. The electrodes are manufactured by selective dissolution of Al from a eutectic composition of Cu17.5Al82.5 using 5 M NaOH. The ostensible (i.e., net...
(pH = 6.8 in CO2-saturated electrolyte and N2 + CO2-saturated electrolyte in 0.1 M KHCO3; pH = 8.3 for N2-saturated electrolyte in 0.1 M KHCO3). All the potentials were recorded relative to the reversible hydrogen electrode (RHE). The high purity N2(99.999% purity) and CO2...

with the existence of magnetite. The elevated viscosity of slag commonly results in a mass of copper losses because of the low sedimentation rate of copper components. Copper is also lost to slag as sulphide, in the absence of an oxidising atmosphere present; or as oxide or silicate in an ...
Driven by the need to biosynthesized alternate biomedical agents to prevent and treat infection, copper oxide nanoparticles (CuONPs) have surfaced as a promising avenue. Cyanobacteria-derived synthesis of CuONPs is of substantive interest as it offers an
