17 Claims

1. A method for producing heterogeneous single atom catalysts comprising:

dissolving at least one catalyst precursor in water to form a solution;

mixing at least one support substrate in the solution;

providing at least one metal precursor to the solution;

preventing precursor agglomeration via dissolving at least one non-water soluble chelating agent in at least one polar solvent and adding this to the solution;

providing and fixating precursor ions during catalyst activation;

anchoring at least one metal precursor to the at least one support substrate, wherein the at least one support substrate comprises TiO₂and/or SiO₂; and

reducing the solution.
