Beschreibung
Zusammenfassung:	Inorganic hydrated metal oxide and metal silicate gels are supported on the surface of particles of porous material by precipitation therein without significant deposit within pores of the suppor t material and without encapsulating the particles of porous material. Especially preferred hydrated oxides and silicate gels are those of titanium. Preferred porous particles are composed of carbon. These novel composite materials are prepared by spraying an aqueo us basic material to the porous particles and then spraying a concentrated aqueous acidic solution of a source of suitable metallic ions so as to rapidly form a gelatinous precipitate on the surface of the porous particles which remain porous.
