Abstract

Without doubt, growing consumption of plastic waste and used batteries causes various environmental problems. Recycling such waste materials and converting them to valuable compounds are considered as an environmentally friendly and economically viable choice. In fact, the use of waste-originated compounds and recycling resources for the preparation of metal − organic frameworks (MOFs) seem to be beneficial to both environmental protection and sustainable economic development. In this regard, a waste-originated MOF compound (W-MOF) was successfully prepared from the zinc-carbon (Zn-C) used batteries and polyethylene terephthalate (PET) waste bottles, both of which served as the pre-precursor agents. In fact, the W-MOF preparation was accomplished by combining Zn(II) ions and terephthalic acid (H₂BDC) precursors recovered from respective Zn-C waste batteries and PET waste bottles. Following that, W-MOF compound was modified with graphene oxide (GO), and the resulting composite (GO-W-MOF) was applied as the catalyst for the photodegradation of two prominent organophosphorus pesticides, namely chlorpyrifos (CPF) and profenofos (PFF). The optimum conditions were set as follows: solution pH 5, the contaminants’ concentration of 1 mg/L, the catalyst dosage of 0.6 g/L, and Vis-irradiation time of 60 min. Additionally, the photodegradation of CPF and PFF well fitted to the first-order kinetic model. Meanwhile, the GO-W-MOF catalyst featured a superb recovery and high stability and a high level of efficiency regarding the treatment of real samples was accomplished as well. As far as the economic and environmental advantages as well as the obtained results are concerned, the applied GO-W-MOF composite, which was derived from the waste recycling process, acted as a suitable catalyst with regard to the photodegradation of CPF and PFF in aqueous solutions.

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.
