Industrial effluents are a leading major threat for water contamination, subsequently which results in severe health associated risks. Hence, purifying wastewater before releasing into the resources is essential to avoid contamination. In this study, ZnO/Cu-DPA nano-composites were prepared by altering percentage of Cu-DPA (20%, 30%, 40%, and 50% denoted be ZnO/20%Cu-DPA, ZnO/30%Cu-DPA, ZnO/40%Cu-DPA ZnO/50%Cu-DPA) using simple mechanical grinding process. Several spectroscopic studies employed such as electron paramagnetic analysis (EPR), powdered X-ray diffractometer (PXRD), UV-Vis absorbance spectroscopy, Fourier transform infrared (FT-IR) spectroscopy scanning microscope characterize these nano-composites. The photo-catalytic activities studied degrading MB under visible light irradiation. ZnO, ZnO/50%Cu-DPA degradation efficiencies determined 71.8, 78.5, 77.1, 66.1%, respectively. Among composite catalysts, ZnO/20%Cu-DPA coupled system demonstrated best efficiency (87%) photo-degradation within 80 min when exposed light. had greater photodegradation than pristine ZnO owing p-n heterojunction linked system. Under irradiation, catalysed conversion dissolved O2 hydroxyl radicals (OH·), triggering reduction MB. This suggests that ·OH primary specific active radical involved decomposition Furthermore, EPR indicates existence proposed (ZnO/20%Cu-DPA) reusability was investigated across three cycles most efficient photo-catalyst. show that, nano-catalyst potential candidate remediation dirty water.

Addition of graphene oxide to ZIF-8/HKUST-1 composite for enhanced adsorptive and photocatalytic removal of congo red in wastewater

South African Journal of Chemical Engineering, Год журнала: 2023, Номер 46, С. 132 - 142

Ternary composites comprised of graphene oxide (GO), ZIF-8, and HKUST-1 with varying amounts GO were successfully synthesized via the solvothermal method. Based on photoluminescence characterization, GO/ZIF-8/HKUST-1 composite presents a more efficient charge carrier separation transfer compared to pristine ZIF-8. As result, electron-hole recombination was hindered due presence as an electron mediator in heterojunction. The dark adsorption kinetics data for removal congo red (CR) dye fit well pseudo-second order model. photocatalytic degradation performance investigated by means degrading CR under UV-LED irradiation. photodegradation efficiency GO(10)/ZIF-8/HKUST-1 91.81% within 60 minutes trapping experiments showed that hydroxyl superoxide radicals are main reactive species. results this study indicate ternary MOFs photocatalysts have great potential pollutants aquatic environments.
