“…Thus far, different methods have been suggested for the synthesis of this composite. [ 253–262 ] Among various techniques for merging the compounds between these two materials, we can name the integration of CuO–reduced graphene oxide (rGO). The process was conducted by the dissolution of CuSO 4 ·5H 2 O in deionized water and GO solution through the co‐precipitation method, [ 263 ] embedding CuO islands in the graphene film, where graphene was grown on polycrystalline Cu foil in a furnace by CVD procedure, [ 264 ] and synthesis of leaf‐like CuO on graphene sheets by a hydrothermal method.…”

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.

“…The intercalation of rGO layers with CuO nanospheres [ 25 ] and np [ 26 ] has also produced enhanced electrochemical properties of the composites over those of the plain metal oxide, with rGO playing a key role in protecting CuO from rapid degradation due to contact with Li + ions, accommodating volume expansion, reducing diffusion paths and improving electron transport. The CuO np /rGO based anode showed a specific capacity of 623 mA·h·g −1 after 100 cycles with 95% Coulombic efficiency, whereas the porous CuO nanospheres/rGO based anode also presented high stability with capacity retention of 90.6% after 50 cycles.…”

Research activity on ceramic/graphene composites and hybrids has increased dramatically in the last decade. In this review, we provide an overview of recent contributions involving ceramics, graphene, and graphene-related materials (GRM, i.e., graphene oxide, reduced graphene oxide, and graphene nanoplatelets) with a primary focus on applications. We have adopted a broad scope of the term ceramics, therefore including some applications of GRM with certain metal oxides and cement-based matrices in the review. Applications of ceramic/graphene hybrids and composites cover many different areas, in particular, energy production and storage (batteries, supercapacitors, solar and fuel cells), energy harvesting, sensors and biosensors, electromagnetic interference shielding, biomaterials, thermal management (heat dissipation and heat conduction functions), engineering components, catalysts, etc. A section on ceramic/GRM composites processed by additive manufacturing methods is included due to their industrial potential and waste reduction capability. All these applications of ceramic/graphene composites and hybrids are listed and mentioned in the present review, ending with the authors’ outlook of those that seem most promising, based on the research efforts carried out in this field.

“…As shown in Figure , the impedance spectrum is composed of two parts: a semicircle in the high frequency region and a straight line in the low frequency region. Among them, the radius of the semicircle represents the charge transfer impedance of the electrode interface, while the straight line indicates the diffusion impedance caused by Li + in the electrode diffusion process, also known as Warburg impedance . Apparently, compared with the cube CuO/C/NF, the octagonal flower‐like CuO/C/NF has the minimum charge transfer impedance, which further indicates that the special CuO/C/NF structure without binder possesses high conductivity and excellent electrochemical performance.…”

At present, the high theoretical specific capacity CuO-based anodes are considered as a potential host for lithium-ion batteries (LIBs). Unfortunately, the intrinsic poor conductivity of metal oxide and the huge volume expansion during the cycling caused serve capacity fading and unsatisfactory cycling stability. Here, a porous free-standing octagonal flower-like copper oxide (CuO)/carbon(C)/nickel foam (NF) multilevel structure is synthesized. The design of carbon-coated ensures excellent mechanical strength, chemical stability and conductivity of nanocomposite, which effectively prevent the collapse and corrosion of the active material during cycle. In addition, 3D interconnected structure shortened the transmission distance of electrons and Li + , improving the ability of fast charge and discharge. The CuO/C/NF electrode exhibits high performance in cycling as the anode material for LIBs. The initial charge/ discharge specific capacity of the octagonal flower-like CuO/C/ NF electrode is 871.1 mA h g À 1 and 916.06 mA h g À 1 at 0.5 A g À 1 , respectively. It achieves an outstanding discharge specific capacity of 505 mA h g À 1 at 2 A g À 1 after 800 cycles. This work combines CuO with a conductive matrix (carbon) and a 3D porous NF, effectively enhancing the electrochemical properties of CuO, which is of certain significance to the further research.
