Efficient binder-free electrode with a derivative synthesis of a four-leaf clover cobalt oxide from a metal organic framework on nickel foam as an energy storage device

“…Designing derivatives from ZIF-67 using post treatments is commonly applied to convert the metal into a compound with great electrocapacitive features. [29][30][31] Also, the large surface area and tunable porous size properties of ZIF-67 could be maintained for ZIF-67 derivatives, and the low electrical conductivity of ZIF-67 could be solved for the ZIF-67 derivatives prepared with post treatment. Chen and co-workers fabricated cobalt oxide nanoparticles using polymer-cobalt acetate and ZIF-67.…”

Graphene quantum dots incorporated ZIF‐67 for stabilization of Au nanoparticles: Efficient catalyst for A3‐coupling and nitroarenes reduction reactions

“…Zeolitic imidazolate frameworks (ZIFs) are considered a new category of porous and crystalline materials having large pore volume, and high surface area, and the advantage of easy functionalization is a special class of metalorganic frameworks (MOFs) 1,2 Among them, ZIF-67 is prepared from tetrahedral cobalt cations and 2-methylimidazolate bridging ligand forming a cubic crystal symmetry in which the angle of Co-Im-Co is $145 and unit cell parameters are a = b = c = 16.9589 A. [3][4][5] ZIF-67 has been used for an array of applications including separation, drug delivery, bioimaging, supercapacitors, and catalysis. [6][7][8] However, modification of ZIF-67 with other components and ligands lets them apply as support for immobilization of other transition metals and benefit from advantages of bimetallic catalysts.…”
