MXenes are an emerging class of two-dimensional transition metal carbides and nitrides with metallic conductivity and hydrophilic surfaces. The discovery of MXenes has opened new possibilities for developing advanced hybrid composites for energy storage and conversion applications. This review summarizes recent advances in developing MXene-based hybrid composites, including their synthesis, characterization, and electrochemical performance. The heterostructure of MXenes with nanocarbons, metal oxides, polymers, and other nanomaterials can overcome the limitations of pristine MXenes and lead to enhanced lithium/sodium-ion storage, pseudocapacitive performance, and electrocatalytic activity. Various fabrication techniques have been employed to synthesize MXene composites with controlled nanostructures, morphology, and interfacial properties. Characterization by microscopy, spectroscopy, and electrochemical methods has shed light on structure-property relationships in these materials. As electrode materials, properly designed MXene hybrids have achieved high specific capacity, excellent rate capability, and long-term stability. The review also discusses strategies for further improving MXene composite energy storage performance, as well as emerging applications such as thermoelectrics and photocatalysis. Continued research to understand interfacial effects and optimize MXene heterostructures holds promise for developing next-generation energy storage technologies.

Nanostructured CdS thin films are essential for efficient electron transport and they act as an ideal buffer layer in CIGS/CZTS/CdTe thin-film solar cells. Herein, low-temperature processed CdS nanostructured thin film on a glass substrate by chemical bath deposition for its application in optoelectronic devices is reported. As synthesized, CdS nanostructured thin films are exhibited polycrystalline, confirmed using X-ray diffraction/transmission electron microscopy. Further, polycrystalline (hexagon/cubic) nature reconfirmed by Raman band at 305 cm-1 of as-grown films. The surface morphology and EDS of CdS thin films reveal uniformity on the surface with non-cuboid nanoparticles and nearly stoichiometric. The optical band gap of CdS nanostructured thin films was found to be 2.3 eV, properties indicating its suitability as a buffer layer in CIGS/CZTS thin-film solar cells.

“…Copper- and zinc-derived oxide materials are used in many catalytic processes due to their accessibility, low price and versatility. It has been reported that CuZn-based systems efficiently catalyze CO 2 reduction [ 5 , 6 , 7 , 8 ], organic pollutants degradation [ 9 , 10 ], and are used in electrochemical sensing [ 11 ]. Subjecting copper–zinc materials to oxidation yields very diverse oxide structures in terms of both chemical composition and morphological features.…”

Herein, we report a feasible method for forming barrel-like hybrid Cu(OH)2-ZnO structures on α-brass substrate via low-potential electro-oxidation in 1 M NaOH solution. The presented study was conducted to investigate the electrochemical behavior of CuZn in a passive range (−0.2 V–0.5 V) and its morphological changes that occur under these conditions. As found, morphology and phase composition of the grown layer strongly depend on the applied potential, and those material characteristics can be tuned by varying the operating conditions. To the best of our knowledge, the yielded morphology of barrel-like structure has not been previously observed for brass anodizing. Additionally, photoactivity under both UV and daylight irradiation-induced degradation of organic dye (methyl orange) using Cu(OH)2-ZnO composite was explored. Obtained results proved photocatalytic activity of the material that led to degradation of 43% and 36% of the compound in UV and visible light, respectively. The role of Cu(OH)2 in improving ZnO photoactivity was recognized and discussed. As implied by both the undertaken research and the literature on the subject, cupric hydroxide can act as a trap for photoexcited electrons, and thus contributes to stabilizing electron-hole recombination. This resulted in improved light-absorbing properties of the photoactive component, ZnO.
