Enhanced Synergistic performance of ZnO@BiOX (X=Cl, Br, I) heterojunction for photocatalytic degradation of emerging pollutants under visible light
In this work, we study the influence of the proportion and halogen type present in heterojunctions of zinc oxide and bismuth oxyhalides ZnO@BiOX (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 % Br- and 25 % Cl- (ZnO@BiOBrCl 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 % of sulfadiazine in 150 min.
期刊介绍：
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
