The degradation of biological and/or organic substances in the liquid phase, especially for sterilizing liquids, comprises reacting a solid metal catalyst with an oxidizing agent and the substance. The solid metal catalyst comprises at least one group I alloy element, at least one group II alloy element, and at least one group III alloy element. The group I alloy elements form only divalent oxides and the group II alloy elements only trivalent oxides below Tamman's temperature in an oxygen atmosphere. The group III alloy elements form oxides in different oxidation states depending on the temperature and gas atmosphere, especially the oxygen partial pressure. An Independent claim is also included for a solid metal catalyst used in the above process. Preferred Features: The catalyst is reacted with oxygen, ozone, nitrogen monoxide, hydrogen peroxide or other peroxide compounds, or mixtures of the above oxidizing agents. The group I alloy elements are nickel, magnesium, barium, calcium and strontium, with nickel forming 0.5-2 times the amount in wt.% of the group II alloy element. The group II alloy elements are chromium, boron, aluminum, gallium and indium, with chromium Cr forming 0.5-2 times the amount in wt.% of the group I alloy element. The group III alloy elements and their common oxidation states are Fe(II/III), Cu(I/II), Mn(II/III/IV), Mo(III/IV/V/VI), W(IV/VI), and V(II/III/IV/V). The catalyst is a wire, sheet metal, foil or foam in the form of a knitted or woven, honeycombed or structured packing.
