In this paper Ag-AgBr nanostructures photocatalytic properties were studied. Hybrid nanoparticles were grown in photo-thermo-refractive glass during the ion exchange in AgNO3 solution and subsequent heat treatment. XRD study  demonstrated the growth of Ag nanoparticles with increase of bromine concentration. Water-dye degradation rate shows that with increase of bromine concentration photocatalytic properties of glass are also increases.
