Abstract
Abstract Magnetic chitosan nanospheres immobilizing cobalt and manganese tetraphenylporphyrins were synthesized and employed as catalysts for the degradation of a model contaminant, methyl orange (MO) under irradiation with a high-pressure mercury lamp, an iodine tungsten lamp, or natural sunlight (NSL), respectively. Scanning electron microscopy showed that the prepared catalysts had a spherical uniformity with average diameters of ca. 300 nm. Catalytic results illustrated that these magnetic metalloporphyrin nanospheres were highly efficient and recyclable catalysts which can be used to degrade MO under NSL, and the nanospheres with Co(II) porphyrin were more active than those with Mn(III) porphyrin.
