“…For all the as-prepared compounds, the cyclic voltammograms are well superposed indicating the relative structural stability under these conditions. The same shape of the CV curves slightly is observed for Nanoplate-like CuO in the presence of LiClO 4 in propylene carbonate [46]. These voltammograms indicate the intercalation/de-intercalation process of Li + ions.…”

Most of the work has been done on the optical properties of the rare earth doped CePO 4 , so there are few studies on the effect of metal ion doping on CePO 4. The doping improves the properties of the compounds and can lead to new properties. It is the first time, that multi-ionic doping process is used in the CePO 4 matrix, in order to improve the ionic conductivity and the electrochemical stability. The low percentage of (Cd 2+ ,Li +), Cr 3+ ,Bi 3+ dopant affect the structure showing a weak decrease in the lattice parameters compared to the CePO 4. Impedance spectroscopy analysis was used to analyze the electrical behavior of samples as a function of frequency at different temperatures. The total electrical conductivity plots obtained from impedance spectra shows an increase of the total conductivity as Li, Crcontent increases. The determined energy gap values decrease with increasingly Li + , Cr 3+ and Bi 3+ doping content. Electrochemical tests showed an improved capacity when increasing the Li + ,Cr 3+ and Bi 3+ content and a stable cycling performance.

“…While the sloped line in low frequencies associates with Li + ion diffusion within the electrode. 10,15 As seen in Fig. 9a, the depressed semicircle of the CuO-NSs/RGO electrode is far smaller than that of pristine CuO electrode, suggesting a low resistance for the CuO-NSs/RGO electrode.…”

“…11,12 To tackle these drawbacks and improve the electrochemical properties, designing novel electrode materials with advanced structures is critical for CuO anodes. To date, porous CuO nanorods, 8 hierarchical CuO microspheres, 13 urchin-like and shuttle-like CuO, 14 nanoplate-like CuO, 15 CuO nanowire, 16 and leaf-like CuO 17 have been synthesized and exhibit enhanced anodic performance due to their improved electrical/ionic conductivity and mechanical stability. In addition, another effective strategy is to incorporate carbonaceous material into the nanocomposites, such as pyrolysis carbon, 11 carbon nanotubes, [18][19][20][21] and graphene.…”

View full text Add to dashboard Cite

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.
