RDF description of Enhanced Synergistic performance of ZnO@BiOX (X=Cl, Br, I) heterojunction for photocatalytic degradation of emerging pollutants under visible light - http://orbis.uaslp.mx/vivo/individual/scopus12366
In this work, we study the influence of the proportion and halogen type present in heterojunctions of zinc oxide and bismuth oxyhalides ZnO%40BiOX (Where X=Cl-, Br-, I- and several binary combinations of them) on the photocatalytic activity in the degradation of rhodamine-B (Rh-B) under visible light, as well as in two important emergent contaminants resorcinol and sulfadiazine. The materials were synthesized by a solvothermal process at 130 °C, starting from ZnO nanoparticles and BiOX precursors (Bi and X=Cl-, Br-, I- ions). It was found that the best combination of halogens was 75 %25 Br- and 25 %25 Cl- (ZnO%40BiOBrCl bromine-chlorine ratio 3:1) forming a Z-type heterojunction with a time constant of τ = 5.6067 min (κ = τ-1 = 0.1784 min−1) in the degradation of Rh-B (C0 = 30 ppm, VRxn = 250 mL). The same composite degraded totally resorcinol in 250 min, and 85.2 %25 of sulfadiazine in 150 min.
