Photocatalytic degradation of methyl orange mediated by a silica coated nanomagnet porphyrin hybrid

• Nanomagnet porphyrin hybrid ( NPH ) was the most effective photocatalyst for degradation of methyl orange dye MO ); The presence aqueous hydrogen peroxide improves catalytic performance non-immobilized ZnP and ; photodegradation efficiency in H 2 O using photocatalysts showed to be time-dependent; Total observed . photocatalytic activity a silica coated nanomagnet corresponding precursors P evaluated under visible light irradiation. performed air, absence peroxide. results show that causing total after 270 min white irradiation (150 mW cm −2 remarkable this , associated with possibility its reuse, makes material promising photocatalyst.
