There is disclosed a method for the convenient storage of material, especially noxious or radioactive material, which method comprises entrapping the material within a solid by bombarding the solid with ions of the material so as to form a concentration of the material within the solid. Forms of apparatus for carrying out this method are also described.

Storage of material

An apparatus for purifying exhaust waste gases including a catalytic element comprising a substrate of metal carrying a surface layer compatible with and supporting a coating of catalytic material, a major proportion of the surface coating of catalytic material comprising an unagglomerated atomic dispersion. An example of such a substrate is an aluminum bearing ferritic steel which has been heat treated in air to form an essentially alumina surface layer.

Apparatus for purifying exhaust waste gases

A catalyst suitable, for example, for the treatment of car exhaust emissions comprises an unagglomerated atomic dispersion, said coated particles being in association with support material compatible with the coated particles, such that the support material and the coated particles are adhered together.
