  • Capacitive deionization electrode
    Patent number: 11845664
    Abstract: A process for the manufacturing of 3D reduced graphene oxide/Fe2O3 material includes the following steps: (i) putting in contact a graphene oxide (GO) water dispersion with an aqueous solution of iron(II) sulfate; (ii) hydrothermal treatment; and (iii) freezing the reaction product obtained in step (ii) at a temperature ??5° C.; and (iv) lyophilisation. A 3D reduced graphene oxide/Fe2O3 material is obtainable by the process and further relates to electrodes for CDI devices having the material. A method for removing ions from a fluid, like saline water, using the capacitive deionization device includes applying a voltage to the electrodes while supplying the fluid into the capacitive deionization device.
