Abstract: Disclosed are methods for forming a supported catalyst and catalysts formed according to disclosed methods. Methods include contacting a catalyst support with a precursor solution and displacing the solvent of the precursor solution (e.g., water) with a second solvent that has a lower surface tension than the first solvent. The second solvent displaces the first solution according to the Marangoni effect. Methods also include activation of the precursor to form a catalyst, e.g., a supported platinum group metal catalyst or the like.
