Nanocomposites of graphene and transition metal oxides are currently explored as efficient electrode materials in electrochemistry where diverse energy storage and generation functionalities can be accomplished. Keeping in view multiple application potentials both in energy storage and hydrogen production, copper-cobalt oxide/graphene (CCO/GO) nanocomposite was prepared by a single-step thermochemical reduction technique assisted by ultrasonication. Prepared CCO/GO nanocomposite characterized via HR-XRD, XPS, HR-TEM, Raman, and FTIR analysis revealed Cu0.3Co2.7O4 cubic spinel type structure forming composite with graphene oxide. The nanocomposite having an overall morphology of custard apple type (∼130 nm) showed multiple functionalities both in electrochemical energy storage and electrocatalysis. From an energy storage prospect, CCO/GO nanocomposite tested to be pseudocapacitive in nature both in a 3-electrode and 2-electrode mode whose specific capacity is ∼5 times higher as compared to parent GO material. Similarly, the nanocomposite displayed excellent redox stability (∼87 % capacitance retention) over 8000 cycles of operations, and the obtained power density of 275 W/kg @ 1 A/g is high in comparison with other graphene-multimetallic oxide composites. Lower OER overpotential (η = 290 mV), HER overpotential (η = 310 mV), and chronoamperometric (CA) stability values demonstrated its superior electrocatalytic activity and established the potential of prepared nanocomposite to act as a dual-mode catalyst in water splitting process.</div></div>","PeriodicalId":18265,"journal":{"name":"Materials Research Bulletin","volume":"188 ","pages":"Article 113417"},"PeriodicalIF":5.3,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143577307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pristine and Gd substituted CoFe2O4 exhibit a ferrimagnetic nature with an enhanced saturation magnetization obtained at x = 0.04 Gd content. The increase of saturation magnetization with Gd substitution is due to the reduction of the spin canting angle, which has been quantized by the Yafet Kittel model. The intrinsic parameters controlling the magnetization are estimated using the Law of Approach to Saturation (LAS) formalism, and a negative magnetocrystalline anisotropy has been identified. Room temperature ferroelectric studies reveal that CoFe2-xGdxO4 induces a weak ferroelectric behavior due to the spin canting and local asymmetry in octahedral-tetrahedral sites. The spontaneous polarization decreases with Gd substitution, and it is due to the impact of the degree of local asymmetry and pinning site concentration in the system. The P-E curve has been simulated by the modified Jiles Atherton's model, which gives an insight into the role of pinning site contribution to the spontaneous polarization of the CoFe2-xGdxO4 system. A significant magnetoelectric coupling coefficient of about 18 mV/(cm.Oe) is obtained for x = 0.08 Gd substituted CoFe2O4, which is higher than the reported spinel ferrites.

It is not surprising that the majority of scientific findings on quaternary chalcogenide are focused on photovoltaic (PV) studies as the specimen first became popular as a less expensive alternative to costly Si for PV applications. Such materials have all the necessary characteristics, including high absorbance, a band gap that is optimal for efficient charge transport, and non-toxic and abundant component elements. It has efficient charge transport for becoming an effective PV source in nanoparticle or thin film form. Not only in solar cell technology but also in many other optoelectronic applications such as photodetectors, fiber optics, charge storage devices, and memory devices, the Cu-based quaternary chalcogenide semiconductors proved to be an efficient material. CuInGaSe2 (CIGS) solar cells have the greatest documented lab conversion efficiency of 23.35 %. But scarcity and high cost of elements like In and Ga are the main obstacles; in order to make the semiconductor less expensive and nontoxic so they might be utilized for commercial purposes, experiments are being done to examine the features of substituting Indium with transition metals. The Cu2ZnSnS4 (CZTS), Cu2NiSnS4 (CNTS), Cu2CoSnS4 (CCTS), Cu2MnSnS4 (CMTS), and Cu2FeSnS4 (CFTS) were evolved as the replacement of CIGS like materials. Almost the maximum properties of CZTS were explored, So researchers are moving toward other quaternary chalcogenides.
