ABSTRACT:
A palladium-on-silica catalyst for the anthraquinone-hydroquinone method of preparing hydrogen peroxide is prepared by adding acid solutions of a palladium compound and of an additive metal salt to an aqueous slurry of silica particles, lowering the pH of the slurry to about 0.8-1.0, then incrementally raising the pH of the slurry to 2.3-2.7, to 3.8-4.2, then to 6.8-7.2, and then reducing the palladium compound to palladium metal.
