BiOCl Flower Photocatalyst Heterostructured with Magnetic Carbon Nanodots $ Bi_{25} %$ FeO_{40} $–g-$ C_{3} %$ N_{4} $ for Visible-Light-Driven Efficient Photodegradation of Tetracycline Hydrochloride
Abstract Magnetic BiOCl flowers were fabricated using a one-pot hydrothermal process by self-assemble of BiOCl nanosheets on magnetic carbon nanodots (MCDs) $ Bi_{25} %$ FeO_{40} $–g-$ C_{3} %$ N_{4} $. The photodegradation activities of the heterojunctions were detected for Tetracycline hydrochloride (TC) as antibiotic target pollutant. The degradation rate of ternary junction was detected to be 6.5 times faster than bare BiOCl. The attractive performance mainly attributed to synergistic effects resulting from the formation of n–p–n heterojunction, especially MCDs can not only provide the high specific surface area, but suppress the recombination of photogenerated electron–hole pairs. Trapping experiments approve that $ h^{+} $ and %$ \bullet {\kern 1pt} {\text{OH}}%$ radicals were the major reactive species, meanwhile %$ \bullet {\kern 1pt} {\text{O}}_{2}^{ - }%$ radicals also involved in the process of TC photodegradation on BiFeCN catalysts, therefore a possible z-scheme reaction mechanism was proposed correspondingly..
