Abstract

2D layered oxide barium metaantimonate (BaSb2O6) was prepared by conventional solid-state method and applied for photodegradation of acid orange under the effect of pH(pH=2,4,6).The crystal structure was characterized by powder X-ray diffraction and infrared reflectance spectrum.The results of photocatalytic performance demonstrated that the maximum photodegradation rate reached 88% within 120min under UV light irradiation at pH=2.The trapping experiment indicated that superoxide anion (·O-2) was the dominant active specie in the process of photodegradation.Furthermore,the cycling running manifested that BaSb2O6 embraced stable photocatalytic activity and structural stability under acidic condition.
