Photoelectrochemical Water‐Splitting Using CuO‐Based Electrodes for Hydrogen Production: A Review

“…The unit cell of Cu 2 O contains six atoms, where the oxygen atoms are coordinated by four copper atoms and can crystallize into a cubic structure. [ 172–176 ] In contrast, CuO has a monoclinic symmetry with the lattice parameters of α = 4.6837 Å, b = 3.4226 Å, c = 5.1288 Å, β = 99.54°, and α = γ = 90°, where the Cu atom is strongly bonded with four oxygen atoms in an approximately square planar configuration. [ 172,173,177 ] Despite the very few reports on the use of CuO compared to Cu 2 O for photocatalytic water splitting application, CuO has shown a higher light‐harvesting ability because of its lower bandgap energy than Cu 2 O.…”

In situ, seed-free formation of a Ruddlesden–Popper perovskite Cs2PbI2Cl2 nanowires/PbI2 heterojunction for a high-responsivity, self-powered photodetector

“…Herein, in the early stage of the loading procedure, the surface diffusion of the Pb-I atoms near the Cs 2 PbI 2 Cl 2 /PbI 2 interface proceeded by the stress concentration, which occurred at the grain boundaries due to material singularities. 43,44 When the Pb-I atoms arrived at the sample surface, they continued to migrate to some specific sites through surface diffusion. Next, the as-obtained Cs 2 PbI 2 Cl 2 nanowires/PbI 2 heterojunctions were used to build the PDs with the simple device Fig.…”

Room Temperature Surface Oxidation by Alkalization of Binder Free CuO Nanostructured Electrode for Enhanced Supercapacitive Performance

“…Such morphology is useful for surface related applications. [ 16 ] For prolonged immersion time (72 h), a well‐defined rice husk like structure developed and formed an agglomerated dense structure. It is also noteworthy that the prolonged reaction also leads to the formation of destructive submicron sized holes which can be observed over the dense CuO covered surface (CuO 72 ).…”
