  • Patent number: 12370523
    Abstract: Fe—Co core-shell nanospheres and a method for producing the Fe—Co core-shell nanospheres are disclosed. Further disclosed is a method of reducing an organic contaminant in a solution by mixing the Fe—Co core-shell nanospheres with the solution. The Fe—Co core-shell nanosphere includes a shell made of a material having a formula CoxFeyO(x+1.5y) and a hollow core. The Fe—Co core-shell nanospheres are produced by mixing cobalt nitrate and iron nitrate in a solvent mixture to form a first mixture and mixing urea with the first mixture to form a second mixture. The solvent mixture is removed from the second mixture to form a powder. The powder is ground to form the Fe—Co core-shell nanospheres.

  • Patent number: 12148568
    Abstract: A poly(vinylphosphonic acid) (PVPA)-(NH4)2MoO4), gel polymer electrolyte can be prepared by incorporating redox-mediated Mo, or similar metal, into a PVPA, or similar polymer, matrix. Gel polymer electrolytes including PVPA/MoX, x representing the percent fraction Mo in PVPA, can be used to make supercapacitors including active carbon electrodes. The electrolytes can be in gel form, bendable and stretchable in a device. Devices including this gel electrolyte can have a specific capacitance (Cs) of 1276 F/g, i.e., a more than 50-fold increase relative to a PVPA system without Mo. A PVPA/Mo10 supercapacitor can have an energy density of 180.2 Wh/kg at power density of 500 W/kg, and devices with this hydrogel structure may maintain 85+% of their initial capacitance performance after 2300 charge-discharge cycles.
