Small metallic particles in colloidal solutions can be used for the production of effective room‐temperature catalysts. Here, a method commonlyused in the structural modification of ceramic suspensions is applied to platinum particles and found to significantly improve the crystalline perfection of the colloid, as demonstrated by high‐resolution electron microscopy.
