  • Publication number: 20220111358
    Abstract: A method for forming a single atom catalyst on a two-dimensional support material involves providing the two-dimensional support material. The two-dimensional support material is combined with at least two heteroatoms and a metal to form a solution. Liquid is removed from the solution to form a material that includes the two-dimensional support material, the at least two heteroatoms, and the metal. The material including the two-dimensional support material, the at least two heteroatoms, and the metal is heated to form the single atom catalyst that includes single atoms of the metal. The at least two heteroatoms bind the single atoms of the metal to, and stabilize the single atoms of the metal on, the two-dimensional support material.
