Photocatalytic degradation of organic dye and tetracycline by ternary Ag(2)O/AgBr–CeO(2) photocatalyst under visible-light irradiation

In this work, CeO(2) nanosheets decorated with Ag(2)O and AgBr are successfully fabricated via a simple sediment-precipitation method. The as-prepared ternary Ag(2)O/AgBr–CeO(2) composite with double Z-scheme construction was analyzed by various analytical techniques. Ag nanoparticles (NPs) used as...

description In this work, CeO(2) nanosheets decorated with Ag(2)O and AgBr are successfully fabricated via a simple sediment-precipitation method. The as-prepared ternary Ag(2)O/AgBr–CeO(2) composite with double Z-scheme construction was analyzed by various analytical techniques. Ag nanoparticles (NPs) used as the electron medium could reduce the recombination of photoelectrons and holes, thus leading to the improvement of photocatalytic performance of these catalysts. Due to the unique structure and composite advantages, the optimal Ag(2)O/AgBr–CeO(2) photocatalysts exhibit the superior tetracycline (TC) degradation efficiency of 93.23% and favorable stability with near-initial capacity under visible light irradiation. This ternary Z-scheme structure materials will be the well-promising photocatalysts or the purification of antibiotic wastewater.
