“…Therefore, pseudocapacitive materials (PCMs) perform an important role in accumulating a large amount of energy in a short period. The most commonly used PCMs are transition‐metal oxides (MnO 2 , NiO, Co 3 O 4 , and Fe 2 O 3 ), transition‐metal sulfides (CoS, MoS 2 , and NiS), and conducting polymers (polyaniline (PANI), polypyrrole (Ppy), and polythiophene (PT)) . Pseudocapacitors deliver much higher capacitance and energy density values than those of carbon‐based materials used in EDLCs because they offer various oxidation states required for efficient charge transfer.…”

Current progress in the advancement of energy‐storage devices is the most important factor that will allow the scientific community to develop resources to meet the global energy demands of the 21st century. Nanostructured materials can be used as effective electrodes for energy‐storage devices because they offer various promising features, including high surface‐to‐volume ratios, exceptional charge‐transport features, and good physicochemical properties. Until now, the successful research frontrunners have focused on the preparation of positive electrode materials for energy‐storage applications; nevertheless, the electrochemical performance of negative electrodes is less frequently reported. This review mainly focuses on the current progress in the development of tungsten oxide‐based electrodes for energy‐storage applications, primarily supercapacitors (SCs) and batteries. Tungsten is found in various stoichiometric and nonstoichiometric oxides. Among the different tungsten oxide materials, tungsten trioxide (WO3) has been intensively investigated as an electrode material for different applications because of its excellent charge‐transport features, unique physicochemical properties, and good resistance to corrosion. Various WO3 composites, such as WO3/carbon, WO3/polymers, WO3/metal oxides, and tungsten‐based binary metal oxides, have been used for application in SCs and batteries. However, pristine WO3 suffers from a relatively low specific surface area and low energy density. Therefore, it is crucial to thoroughly summarize recent progress in utilizing WO3‐based materials from various perspectives to enhance their performance. Herein, the potential‐ and pH‐dependent behavior of tungsten in aqueous media is discussed. Recent progress in the advancement of nanostructured WO3 and tungsten oxide‐based composites, along with related charge‐storage mechanisms and their electrochemical performances in SCs and batteries, is systematically summarized. Finally, remarks are made on future research challenges and the prospect of using tungsten oxide‐based materials to further upgrade energy‐storage devices.

“…As illustrated in Scheme , being irradiated by visible light, the Ru(bpy) 3 2+ complex will be motivated to the excited state of Ru(bpy) 3 2+* . The Ru(bpy) 3 2+* species would then experience a reductive quenching by the electron donor TEOA to generate the reduced state [Ru(bpy) 3 ] + . Afterward, the excited electrons of the reduced ruthenium complex will delocalize and migrate to the NiCo 2 S 4 catalyst to reduce the CO 2 molecules adsorbed on the surface, leading to the CO evolution; while the photosensitizer recover to the initial state.…”

Mixed metal oxides with a spinel structure have exhibited great opportunities for photocatalytic CO2 reduction; however, the abilities of their sulfide counterparts in this promising area are much less reported. Herein, we demonstrate the synthesis of a ternary metal sulfide, namely NiCo2S4, and its first application to catalyze the CO2 photoreduction reaction under visible light irradiation. The NiCo2S4 material is prepared through a coupled solvothermal‐ion exchange strategy, and is fully checked by diverse characterizations, including X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), energy‐dispersive X‐ray spectroscopy (EDX) and N2 sorption measurements. Under visible light irradiation in a classic tandem photochemical system, this non‐noble‐metal NiCo2S4 catalyst affords a considerable activity and high stability for CO2 deoxygenative reduction, delivering a high CO‐liberating rate of 43.5 μmol mg−1 h−1. The in‐situ PL and transient photocurrent measurements reveal that the spinel catalyst can hamper recombination and accelerate transfer of light‐excited charge carriers, and thus boosting the CO2 reduction reaction. At last, a possible mechanism of the NiCo2S4‐catalyzed CO2 photoreduction reaction is proposed.

“…because the latter suffer from large volume expansion and related rapid capacity decay. [17] Among Cu based TMDs, Cu 2 SnS 3 has been used for Li-and Na-ion batteries in the form of various nanostructures as well as in composite forms. The compounds containing Sulphur (S) face additional issues, namely a) limited active material utilization, b) insulating nature of the discharge products Li 2 S and Li 2 S 2 , and c) the dissolution of polysulfides (Li 2 S n , n higher than 4) into electrolyte that leads to the rapid capacity decay and short cycle life of the battery.…”

With the evolution of Li-ion batteries, they have been employed in many applications. However, high energy density and power density batteries are yet to be developed to meet the necessities at the application end. Sulfides are a good choice as anode material as they show a much higher specific capacity than conventional graphite anodes. But unfortunately, sulfide dissolution and polysulfide shuttling are big drawbacks for their operation. Herein, single phase ternary metal sulfide Cu 3 SnS 4 (CTS) nanoparticles are synthesized with high Cu : Sn ratio and examined for application as Li-ion battery anode. High specific capacities of 1082 mAh g À 1 at 0.2 A g À 1 and 440 mAh g À 1 at a high rate of 3 A g À 1 are realized with superior stability tested up to 950 cycles. Utilizing the CTS NPs can minimize the polysulfide dissolution. The high Cu : Sn ratio provides excess Cu atoms as the buffer matrix for volume expansion of Sn, leading to high stability and specific capacity. Compared to other reported Cu based mixed phase or composite ternary sulfide materials, the CTS NPs presented herein show a better performance. In a full cell device using LiCoO 2 (LCO) as cathode, a good performance is achieved as well with an energy density of 405 Wh/Kg at 0.1 A g À 1 . V-10 mA battery tester. The impedance and cyclic voltammetry were performed with VMP3 biologic system equipped with potentiostat and galvanostat channels.
