“…Photoelectrochemical (PEC) water splitting is one of the promising procedures to generate hydrogen as a zero‐emission energy carrier alternative to polluting fossil fuels. [ 11–20 ] During the PEC water splitting, solar energy can facilitate the occurrence of the hydrogen production half‐reactions at an electrode coated by specialized semiconductors or PEC materials.

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.

“…Also, electrodes that were exposed to light illumination for a long period of time are corrosion prone. This demands a stability test of the photoelectrodes before carrying out the analysis [38,39]. Therefore, a stability test of Sn 0.05 Zn 0.95 O has been done under light illumination for a duration of *3 h without applying a bias voltage.…”

Sn-doped ZnO nanorods (NRs) were grown on a conductive iodine-doped tin oxide substrate with a cost-effective two-step method (sol-gel and hydrothermal). The effect of varying concentration of dopants on morphology and photocurrent density is closely investigated. For microstructural and optical analysis, the bare and Sn-doped ZnO NRs were subjected to field emission scanning electron microscope (FESEM), energy-dispersive spectroscopy, X-ray diffraction, UV-Vis, and Raman spectroscopy. The presence of the most intense peak directed to (0002) plane confirmed the growth of ZnO NRs and their vertical alignment towards c-axis. The impact on nucleation density and morphology due to the addition of dopant was revealed by the FESEM images. The Raman analysis also confirmed the wurtzite nature of ZnO NRs along with the impact of dopant in its crystallinity. The aim of this work was to ameliorate the capability of absorbing solar light in the visible range. Sn 0.05 Zn 0.95 O exhibited highest photocurrent density among all the doped samples with 0.199% photoconversion efficiency under visible-light illumination. Therefore, the synthesised Sn 0.05 Zn 0.95 O seems to be an efficient candidate for photoelectrochemical water-splitting application.

The photoelectrochemical (PEC) properties of nanoflake-like cadmium sulfide (CdS) sensitized zinc stannate (Zn 2 SnO 4 ) heterostructure prepared by spray pyrolysis technique and chemical bath deposition (CBD) are investigated in detail. The crystallinity and surface morphology of the Zn 2 SnO 4 and CdS films are evaluated by X-ray diffraction (XRD), and scanning electron microscope, whereas its optical properties are analyzed by UV-VIS spectroscopy. Zn 2 SnO 4 exhibits uniform granular structure and it has well defined reflection along (311) plane revealing inverse-spinel cubic structure. Zn 2 SnO 4 showed band gap of 3.8 eV, it is well agreeing with the literature. The CdS films fabricated by CBD exhibited nanoflake-like structures. The XRD pattern of the CdSsensitized Zn 2 SnO 4 heterostructure exhibits a mixed phases of the zinc stannate and CdS. The PEC properties of the Zn 2 SnO 4 -CdS heterojunction are studied by using a three-electrode electrochemical cell in a Na 2 S electrolyte. Zn 2 SnO 4 -CdS system has shown 0.8 mA/cm 2 photo-current density whereas with increasing CdS layer thickness it has shown marginal enhancement up to 2.2 mA/cm 2 . The stability of the Zn 2 SnO 4 -CdS heterojunction is outstanding up to 300 s. The results demonstrate that Zn 2 SnO 4 -CdS heterojunction could be a potential material in PEC and solar cell applications.
