“…272 Another important application of photo-thermal catalysis is removal of VOCs (volatile organic compounds) via catalytic oxidation, as reported by Jia and coworkers. 273 They tested four ACo 2 O 4 (A = Ni, Cu, Fe, Mn) type spinels for photo-thermal degradation of toluene, and they observed the superior activity of NiCo 2 O 4 due to better structural and photophysical features. Xu and co-workers reported the synthesis of a SmCoO 3 /SBA-15 composite via an impregnation method, which confers to the material an outstanding surface area.…”

“…However, unlike the traditional photo-catalysis approach, the recent photo-thermo-catalysis efficiently utilises the entire spectrum of solar energy (UV, Visible and IR) for the degradation of organic recalcitrant materials. This is well established by Chen et al [127] is a result of its poor light absorption capacity. This in turn leads to a lower photon count to induce a significant photo-thermal effect.…”

“…This in turn leads to a lower photon count to induce a significant photo-thermal effect. Additionally, Chen et al [127] also concluded that their Co based catalysts were completely inert for photocatalytic degradation of toluene. This was ascribed to the low redox potential nature of Co-based catalysts (< 2.44 vs NHE) which was inadequate for toluene oxidation which had a lighter redox potential (2.61 vs NHE).…”

It is well established that the excessive and uncontrolled use of fossil fuels and organic chemicals have put a risk to the earth‘s environment and the life that sustains within it. Carbon‐free, sustainable, alternative energy technologies have therefore become the prime focus of current research. Smart inorganic materials have emerged as the potential solution to suffice energy needs and remediate the organic pollutants discharged to the environment. One such promising, versatile material is FeCo2O4 which has gained immense research interest in the present decade due to its high efficiency and performance in energy and environmental applications. Innovative material design strategies involving the interplay of nanostructured morphology, chemical composition, redox surface states, and defect engineering have significantly enhanced both electrochemical and catalytic properties of FeCo2O4. Therefore, this review article aims to provide the first‐ever comprehensive account of the latest research and developments in design‐synthesis strategies, characterization techniques, and applications of nanostructured FeCo2O4 and its composites in various electrochemical as well as catalytic applications. A detailed account of the nanostructured FeCo2O4 and its composites in various energy storage and conversion devices such as supercapacitors (SCs), batteries, and fuel cells has been presented. Furthermore, a special section has been devoted to highlight the role of FeCo2O4 in enhancing the sluggish reaction kinetics of oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in water splitting application. This review also highlights the role of nanostructured FeCo2O4 in photocatalytic waste water treatment, gas sensing, and dual‐phase membrane technologies wherein FeCo2O4 has demonstrated promising performance.

“…Recently, mixed metal oxides with a spinel structure, for example, ZnCo 2 O 4 , [32] NiCo 2 O 4 , [33][34] CuCo 2 O 4 , [35] and MnCo 2 O 4 , [36] have been developed as active catalysts for photochemical CO 2 reduction by the cooperation of appropriate photosensitizes, due to their plentiful redox functions, high chemical stability, and rich optical and electronic features. [37] In comparison, ternary metal sulfides possess the advantages of high electrical conductivity, low electronegativity, rich redox properties and suitable band structures, which are favorable features to photocatalytic CO 2 reduction. [38][39][40] Based on all these considerations aforementioned, it may be highly desirable to exploit the functions of spinel metal sulfides for photocatalytic CO 2 reduction reactions.…”

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.
