Organic‐inorganic composites can be used to tailor the properties of inorganic materials. A method of controlling the distribution and dispersion of platinum in platinum‐loaded silica using organic‐inorganic compounds prepared in two different ways is described, and an explanation for the unexpected formation of rings of platinum dots on the silica surface (see Figure) is proposed.
