Abstract: Pyrophorically activated metals are suitable catalysts for electrolyzing water and for other reactions in which nickel or platinum are catalysts. Pyrophoricity can be eliminated without destroying the catalytic effects. Protective coverings can protect and preserve the pyrophoricity. Raney type activation leaves a little aluminum in the activated metal and this aids in catalytic action.

Abstract: Macrosized catalysts suitable for promoting chemical reactions, especially to reduce pollutants in waste gas streams such as automobile exhaust, are described. The catalysts have one or more metal components, especially a platinum group metal component, as a catalytic promoter combined with a high surface area, refractory oxide support on a relatively catalytically-inactive carrier, especially a monolithic carrier which may be of the honeycomb type. An aqueous solution of an alumina precursor is added to the macrosize catalyst to provide protection against poisoning by extraneous materials such as lead, zinc, other metals, sulfur or phosphorus with which the catalysts may come in contact during use.

Abstract: Under oxidizing conditions, a ruthenium catalyst system which is not protected will lose ruthenium by volatilization. A method is taught in this specification for stabilizing a ruthenium catalyst system against such volatilization under oxidizing conditions. The method is carried out by applying to a catalyst substrate a ruthenium catalyst system in which the catalytic material under oxidizing conditions is of the type La.sup.+3 Ni.sub.x.sup.+3 Ru.sub.1-x.sup.+3 O.sub.3 wherein x is in the range from 0.1 to 0.9.
