“…[ 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. [ 178–181 ] Also, the theoretical photocurrent densities for CuO and Cu 2 O are 35 and 14.7 mA cm −2 , respectively, suggesting the superiority of CuO.…”

The cost‐effective, robust, and efficient electrocatalysts for photoelectrochemical (PEC) water‐splitting has been extensively studied over the past decade to address a solution for the energy crisis. The interesting physicochemical properties of CuO have introduced this promising photocathodic material among the few photocatalysts with a narrow bandgap. This photocatalyst has a high activity for the PEC hydrogen evolution reaction (HER) under simulated sunlight irradiation. Here, the recent advancements of CuO‐based photoelectrodes, including undoped CuO, doped CuO, and CuO composites, in the PEC water‐splitting field, are comprehensively studied. Moreover, the synthesis methods, characterization, and fundamental factors of each classification are discussed in detail. Apart from the exclusive characteristics of CuO‐based photoelectrodes, the PEC properties of CuO/2D materials, as groups of the growing nanocomposites in photocurrent‐generating devices, are discussed in separate sections. Regarding the particular attention paid to the CuO heterostructure photocathodes, the PEC water splitting application is reviewed and the properties of each group such as electronic structures, defects, bandgap, and hierarchical structures are critically assessed.

Cupric oxide nanoparticles were synthesized with different morphologies by an electrochemical route, modifying the orientation of the electrodes. Cuprous oxide nanoparticles get to be present. The process consisted in the use of a two-electrode cell powered by one DC voltage source without additional controls. The experiments were carried out at 1 V at 25°C under strong stirring. A copper sheet of 99.98% purity was used as the sacrificial anode, stainless steel sheet as the cathode, and aqueous sodium nitrate as the electrolyte. Structural characterization was done by X-ray diffraction, and the morphology was analyzed by scanning electron microscopy. Using the vertical configuration cupric oxide nanosheets were obtained, while cupric-cuprous oxide shuttle-like nanoparticles were obtained using the horizontal configuration.
