Abstract
A nanocomposite has a core-shell structure with an outer shell and an inner core. The outer shell is a graphitized carbon film, and the inner core contains nickel oxide and alumina, with a nickel oxide content of 59%-80%, an alumina content of 19%-40%, and a carbon content of not more than 1%, based on the total weight of the nanocomposite. The process for catalytic combustion of volatile organic compounds may utilize the nanocomposite as a catalyst.
Claims24
A carbon-coated nickel-aluminum nanocomposite, comprising a core-shell structure with an outer shell and an inner core, wherein the outer shell is a graphitized carbon film, wherein the inner core consists substantially of nickel oxide and alumina, wherein the carbon-coated nickel-aluminum nanocomposite has a nickel oxide content of 59%-80%, an alumina content of 19%-40%, and a carbon content of not more than 1%, and an elemental nickel content in an amount of not more than 1%, based on a total weight of the carbon-coated nickel-aluminum nanocomposite, and wherein the graphitized carbon film is substantially composed of graphitized carbon.
