Carbon Layer Coated Ni₃S₂/MoS₂ Nanohybrids as Efficient Bifunctional Electrocatalysts for Overall Water Splitting

Developing active, stable, and cost‐effective water splitting catalysts is a critical step towards a sustainable energy future. Heterostructures of transition metal chalcogenides have emerged as important candidates for catalyzing oxygen evolution reaction (OER) or hydrogen evolution reaction (HER), due to the synergistic effects originating from the increased active sites or accelerated electron transfer. Current limitation to this strategy lies in the complication of synthesis often resorting to the direct growth of hybrid structures on a conductive current collector. Here, a simple approach is selected to synthesize graphitic carbon layer coated Ni3S2/MoS2 heterostructures (denoted as NMC) with a facile scaffold‐free solvothermal method followed by controlled pyrolysis. The NMC obtained at 600 °C behave as durable, efficient oxygen and hydrogen evolution electrodes with overpotentials of 350 mV and 233 mV respectively at 10 mA cm−2 in 1.0 M KOH. In addition, the catalysts demonstrate a high efficiency for overall water splitting. Such architected catalyst designs may shed light on the development of more efficient bifunctional electrocatalysts.

“…A very rare electrocatalyst of MoS 2 has also been attempted recently to use in MOR. A group of Liu and coworker 259 have combined ultrathin 2D MoS 2 nanosheets with CoNi‐zeolitic imidazole frameworks (ZIFs) with a facile procedure involving hydrothermal method without requirement of calcination and pretreatment of MoS 2 . The ZIFs is a type of MOF, which were functioned to tailoring porous nanocarbon frameworks.…”

Summary Direct liquid fuel cell (DLFC) is one of the leading fuel cell types due to their great features of superior energy density, modest configuration, small size in fuel container, immediate boosting, and effortless storage and carriage. Commercially used liquid fuel types are prepared using alcohols, such as methanol or ethanol, glycol, and acids. DLFCs face great challenges although they are potentially far‐reaching depending on the expensive catalysts and the use of high‐loading catalyst. More questions that should be addressed to ensure excellent DLFC performance include cathode flooding, fuel crossover, numerous side yield production, fuel security, and unverified elongated‐duration robustness. Further studies need to be carried out to ensure the continuous improvement of the quality of DLFCs' performance and their penetration in the commercial market. To date, direct liquid fuel cells made of methanol and ethanol have been successfully produced in commercial scale, but other types of DLFCs are still under study. In this review, introduction to DLFC will be discussed by covering work and commercialization as well as recent progress and challenges encountered.

The human craving for energy is continually mounting and becoming progressively difficult to Gratify. At present, the world's massive energy demands are chiefly encountered by nonrenewable and benign fossil fuels. However, the development of dynamic energy cradles for a gradually thriving world to lessen fossil fuel reserve depletion and environmental concerns are persistent issues for society at present. The discovery of copious nonconventional resources to fill the gap between energy petition and supply is the extreme obligation of the modern era. A new emergent, clean, and robust alternate of fossil fuels are the fuel cells. Among the different types of fuel cells, direct methanol fuel cells are an outstanding option for light-duty vehicles and portable devices. A critical tactic for striving and sustainable energy sources is the production of highly proficient, economical, and green catalysts for energy storage and conversion devices. Up till now a broad range of research work is available to use Pt and modify Ptbased electrocatalysts to augment the CH 3 OH oxidation process. Platinum-based nanocubes, nanorods, nanoflower, hybrids of Pt with metal-oxides such as Fe 2 O 3 , TiO 2 , SnO 2 , MnO, Cu 2 O, ZnO, and with conducting polymers are extensively utilized in both acidic and basic media. Moreover, Pd-based materials, transition metal-based materials as well as MOF and MOF-derived materials are also the point of interest for researchers nowadays. However, the problem associated with their practical applications is that they can be effectively employed in basic media due to comparative less stability in acidic medium. This review article will deliver a broad vision of the current progress of the MOR process concerning noble metals, transition metals, and MOF-based materials.
