摘要	We herein prepared defective Bi2O2CO3 microspheres via a simple nitric acid treatment method. Upon generation from Bi2O2CO3, electrons and holes were superbly separated with the existence of defects. Combined with the advantages of multiple scattering and reflection, a large surface area and increased range of visible-light absorption, the defective Bi2O2CO3 dispalyed a high efficiency for the photodegradation of HCHO gases and methyl orange. The defective Bi2O2CO3 also possessed a superior stability, which is important for practical applications. This work opens up new opportunities for the design and fabrication of high-activity Bi-based photocatalysts for environmental protection.
