Independent claims are also included for the following: (1) a solution containing the colloid; (2) a method of preparing the colloid solution in which precious metals salt(s) are reacted with reducing agent(s) in the presence of the oxidation-insensitive stabilizing polymer(s); (3) a precious metal heterogeneous catalyst containing the precious metal colloid and a support.",
