  • Publication number: 20220184702
    Abstract: A method of forming a metal nanomaterial comprises forming a precursor solution comprising a metal precursor and a metal oxide precursor. A complexing agent is added to the precursor solution, and the metal precursor and the metal oxide precursor are hydrolyzed to form a sol. The sol is heated to form a gel, which is calcined to incorporate metal cations from the metal precursor into a metal oxide lattice from the metal oxide precursor. The calcined gel is exposed to a reducing agent to exsolve the metal from the metal oxide lattice and to form a metal nanomaterial comprising a metal and a metal oxide is formed. Additional methods of forming a metal nanomaterial are also disclosed.
