Sonocatalytic degradation of norfloxacin in aqueous solution caused by a novel Z-scheme sonocatalyst, mMBIP-MWCNT-In2O3 composite

A novel Z-scheme composite sonocatalyst, mMBIP-MWCNT-In2O3, is successfully fabricated by using hydrothermal and calcination methods. The sonocatalytic activity of mMBIP-MWCNT-In2O3 composite is evaluated through the degradation of norfloxacin under ultrasonic irradiation. The addition of MWCNT accelerates the electron (e−) transfer and restrains the recombination of electrons (e−) and holes (h+) in Z-scheme mMBIP-MWCNT-In2O3 sonocatalyst. In comparison with the individual components (mMBIP or In2O3), the formation of Z-scheme sonocatalytic system and the presence of and MWCNT make the mMBIP-In2O3 display much higher activity in the degradation of norfloxacin. It is wished that the mMBIP-MWCNT-In2O3 composite would be an available catalyst in sonocatalytic degradation of organic pollutants.249
