IODINE DOPED BISMUTHYL CARBONATE NANOSHEET AND MOLYBDENUM DISULFIDE MODIFIED CARBON NANOFIBER COMPOSITES, PREPARATION METHOD AND APPLICATION THEREOF

摘要

Iodine doped bismuthyl carbonate nanosheet and molybdenum disulfide modified carbon nanofiber composites, preparation method and its application in wastewater treatment are disclosed. Bismuth citrate and sodium carbonate as precursors, sodium carbonate as a precipitating agent, dispersed in a mixed solution of water and ethylene glycol, sodium iodide as a iodine source, nano carbon fiber membrane act as the carrier, to synthesis carbon fiber membrane that modified by iodine-doped Bi₂O₂CO₃ nanosheets; then sodium molybdate and thioacetamide as precursors, dispersed in water to react to obtain iodine doped bismuthyl carbonate nanosheet and molybdenum disulfide modified carbon nanofiber composites. The composite material synthesized through a series of steps exhibit excellent photocatalytic activity for the degradation of Rhodamine B and can be recycled for many times. And this invention has the advantages of simple preparation process, easy recovery and multiple use, etc., and has industrial application prospect in water pollution treatment.
