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.

A carbon-coated nickel-aluminum nanocomposite, characterized in comprising a core-shell structure with an outer shell and an inner core, wherein the outer shell is a graphitized carbon film, and the inner core comprises 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.
A process for preparing a carbon-coated nickel-aluminum nanocomposite, characterized in comprising the steps of:
- preparing a nickel-aluminum precursor;
- carrying out a heating treatment on the nickel-aluminum precursor, and carrying out a vapor deposition by using a lower alkane as a carbon source gas;
- and
- carrying out oxygen treatment on the product obtained after the vapor deposition, to provide the nanocomposite.
