“…Ni and Co MOFs were found to be crystalline, on the other hand, Ni/Co-MOF was highly crystalline in comparison with Ni and Co MOFs as observed from XRD patterns. The XRD pattern of Ni-MOF exhibits diffraction peaks at 11.8°, 18.01°, 20.83°, 22.28°, 23.83°, and 33.48°, corresponding to (11-1), (150), (151), (220), (02-4) and (025) planes of Ni-MOF, respectively [26]. The diffraction pattern of the Co-MOF is in good agreement with the literature [27] and XRD pattern of Ni/Co-MOF exhibits evident diffraction peaks similarity with literature, probably have the layered topology crystal structure which is built by connected central metal ions with BDC ligands to form a 2D layered structure [9].…”

Metal-organic framework (MOF) of Ni-MOF, Co-MOF, and Ni/Co-MOF were synthesized by a facile hydrothermal method using Trimesic acid as structure directing linker. The physico-chemical properties of the synthesized MOFs were characterized by P-XRD (powder X-ray diffraction), FT-IR (fourier transform infrared spectroscopy), SEM-EDS (scanning electron microscopy/energydispersive X-ray spectroscopy), HR-TEM (high-resolution transmission tlectron microscope) and BET (Brunner Emmett Teller) surface area techniques. The supercapacitance performance of these MOFs were studied by electroanalytical techniques such as cyclic voltammetry (CV), chronopotentiometry (CP) and electrochemical impedance spectroscopy (EIS). Amongst the MOFs investigated, Ni/Co-MOF exhibited highest specific capacitance (C s ) of 2041 F g −1 at a scan rate of 2 mV s −1 and 980 F g −1 at a current density of 2.5 A g −1 . Ni/Co-MOFs delivered a maximum energy density (ED) of 55.7 W h Kg −1 at a corresponding power density (PD) of 1 K W kg −1 and maximum PD of 9.8 K W kg −1 at an ED of 41.6 W h Kg −1 . An outstanding supercapacitance performance with superior columbic efficiency of 98.4% and capacitive retention of 73% after 5000 cycles marks this material as potential candidate for supercapacitors (SCs). A comparative electrochemical study of these MOFs were made in three electrode system, further electrochemical performance was corelated with their physico-chemical properties.

“…The initial weight loss before at 150 °C is due to the removal of water content. Further, it can be seen that the rapid weight loss after around at 350 °C has probably broken down the structure of MOFs, suggesting that this might be a transformation of Ni‐MOF into HP‐Ni@C‐N . The high specific surface area and porosity of the sample are of importance for electrochemical application including hydrogen and oxygen evolution reaction and in supercapacitor.…”

Metal‐organic frameworks (MOFs) have emerged as one of the most outstanding innovated and functional materials for electrochemical application. Here, the structure of novel MOFs‐derived hierarchically porous Nickel@Carbon nanospheres (HP‐Ni@C‐N) synthesized via pyrolysis after the solvothermal reaction is discussed. The method includes the decomposition of the trimesic acid as an organic molecule at a specific temperature of transformation into a carbon matrix wrapping of nickel nanoparticles (Ni NPs). Furthermore, HP‐Ni@C‐N supported on nickel foam as an electrochemical energy storage supercapacitor application and obtained 912 F g−1 at 10 mV s−1 is reported. Interestingly, the covalent bridge between the Ni core and carbon shell facilitates the faster ions transportation. Therefore, it is presumed that this work can be informative and elucidative for the construction of MOFs‐derived transition metals hybrid nanostructures.

“…18 Ultrasonic technology is no doubt recognized as one part of the emerging science and technology. Due to its easy operation, high efficiency, and environmental-friendly rapid processing, it is applied extensively in synthesis of materials, 21,22 disinfection, 23 and wastewater treatment. 24 High shear forces generated by acoustic cavitation can result in homogeneous distribution in aqueous solution, 25 so it may be applied to distribute and assemble cationic microblocks during the process of template polymerization.…”
