Palladium-containing catalysts that exhibit fast kinetics in oxidation of reducing gases such as hydrogen, carbon monoxide, and hydrocarbons have been prepared. Palladium, as oxide and/or hydroxide, is deposited on various metal oxides and metal sulfates. The kinetics of palladium oxide reduction has been increased by the addition of precious metal group such as platinum, silver, and ruthenium salts and complexes. This invention can be used in development of chemochromic passive sensors for hydrogen, carbon monoxide, and hydrocarbon gas detection. These gases/liquids are widely used and produced in many industries and a safe operation is a number one priority for all of them. These pigments will provide a layer of protection against accidental releases of these gases and therefore reinforces a safe manufacturing/utilization environment. When used as chemochromic hydrogen leak detection sensor, this novel doping technique has increased the pigments sensitivity toward hydrogen gas by 3 folds while encapsulated within a silicon resin.
