A catalytically active glass-ceramic and method for producing a catalytically active multi-phase glass-ceramic in which at least one catalyst precursor is mixed with a glass-ceramic precursor formulation to form a catalyst precursor/glass-ceramic precursor mixture. The catalyst precursor/glass-ceramic precursor mixture is then melted to form an amorphous glass material which, in turn, is devitrified to form a polycrystalline ceramic. The polycrystalline ceramic is then activated, forming a catalytically active multi-phase glass-ceramic.
