Disclosed is a palladium catalyst supported on silica which can be used in the hydrogenation reaction of anthraquinones in a hydrogen peroxide production process utilizing an anthraquinone method and which is excellent in activity, strength, life and selectivity. Palladium is supported on a silica carrier having an average pore diameter in the range of 80 to 400 .ANG., or spherical silica particles, at least 90 wt% of which have a particle diameter in the range of 10 to 100 µm and which have an average particle diameter in the range of 30 to 60 µm and a pore volume is in the range of 0.4 to 1.0 ml/g; or palladium and an alkali metal are supported on a silica carrier, and the amount of the alkali metal is in the range of 0.1 to 5 wt% based on the weight of the silica carrier.
