“…For the evaluation of electrochemical performance of synthesized MOFs by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), Chronoamperometry (CA) measurements, catalytic ink was prepared by mixing catalyst (2 mg), ethanol (100 µL) and 5 wt% solution of Nafion (20 µL) [36]. The resulting suspension was coated onto a glassy carbon electrode (GCE) with the help of a micro pipette.…”

In this work a novel bimetallic nickel oxide/copper oxide metal–organic framework (NiO/CuO MOF) has been developed by using two linkers: Benzene Dicarboxylic acid (BDC) and Pyrazine. The composites of NiO/CuO MOF with different amounts of reduced graphene oxide (rGO) were synthesized through a hydrothermal method and subsequently characterized by multiple significant techniques like XRD, SEM, EDX, FTIR and Raman IR for an investigation of their structural and morphological properties. The prepared series of material was later employed for electrochemical oxidation of methanol, tested by cyclic voltammetry (CV) in basic medium on a modified glassy carbon electrode (GCE). The electrochemical response depicts that increasing concentration of rGO enhances the electrocatalytic activity of the catalyst for methanol oxidation reaction (MOR). The catalyzed oxidation reaction of methanol by NiO/CuO MOF and rGO-NiO/CuO MOF composites give a superlative current density of 437. 28 mA/cm2 at 0.9 V potential at 50 mV/s scan rate. This activity makes it a promising catalytic material for electrolysis of methanol in direct methanol fuel cell (DMFC).

“…Hydrothermally synthesized irregular-shaped nanoparticles possess low resistance (252 Ω), high diffusion co-efficient, and maintenance of the maximum amount of current density (275.8 mA/cm 2 ) for 3600 seconds in an alkaline medium. 180 Yaqoob et al, in 2019, fabricated Ni-benzene tricarboxylic acid MOF and its rGO composites by employing a one-pot solvothermal technique and thoroughly studied their electrocatalytic activity toward MOR in an alkaline condition. Among the synthesized MOF-rGO composite series, an optimized sample, Ni-BTC 4 wt% rGO delivers a current density of 200.02 mA/cm 2 at peak potential of 1.65 V vs RHE.…”

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.
