In order to mitigate the environmental impact of polyethylene terephthalate(PET)plastic pollution and enhance waste resource utilization;we developed a novel Ir-ReO_(x)/SiO_(2)+HZSM-5 catalytic system for the hydrodeoxygenation(HDO)of PET plastic wastes into cycloalkanes;particularly 1;4-dimethylcyclohexane(DMCH).Under mild conditions(190℃;3 MPa H_(2))with a certain amount of water in cyclopentane solvent;the highest yield of DMCH reached 95.8%;contributing to an overall yield of cycloalkanes at 98.4%within a reaction time of 4 h from HDO of virgin *** HDO of PET into DMCH involved initial hydrogenation of PET aromatic ring;then depolymerized by direct hydrogenolysis of acyl C-O bond in the ester group and subsequent cascade HDO of alcoholic C-O bond to saturated ester and alcohol intermediates;and further HDO of these oxygenates converting into desired DMCH *** Ir-ReO_(x)/SiO_(2) catalyst exhibits fully reduced metallic Ir nanoparticles along with partially reduced ReO_(x) species that are highly dispersed on both SiO_(2) surface and Ir nanoparticle *** oxophilic nature of ReO_(x) species facilitates the activation of C-O bonds;the acidic HZSM-5 zeolite for the promotion of dehydration reaction;and the protic property of H_(2)O for the enhancement of hydrogenation PET contributed to highly HDO activity of this ***;the catalytic system is applicable for the HDO of diverse real-world PET plastic wastes including Coca-ColaTM bottles;green Sprite bottles and white and red discarded fiber cloths;generating DMCH with a yield of up to 95.9%and cycloalkanes with a yield of up to 99.5%.This innovative process presents a new avenue for efficient hydrodeoxygenation conversion of PET into easily separable DMCH which serves as a crucial building block for the production of terephthalic acid to realize the chemical recycling of PET plastic wastes towards a green circular economy.

Ribavirin (RBV), which is extensively used to treat viral diseases such as COVID-19, is considered one of the major emerging contaminants due to its long-term existence and health risk in the aqueous environmental system. However, research on effective removal of RBV still remains insufficient. In this study, we investigated the RBV degradation kinetics and mechanism in UV/chlorine/Fe(II) process. The degradation rate constant kobs-RBV of RBV was 2.52 × 10−4 s−1 in UV/chlorine/Fe(II) process, which increased by 1.6 times and 1.3 times than that in chlorine alone and UV/chlorine process, respectively. Notably, trace amount Fe(II) promoted RBV degradation in UV/chlorine system through Fe2+/Fe3+ cycles, enhancing the yield of reactive species such as HO· and certain species reactive chlorine radicals (RCS). The contributions of HO· and RCS toward RBV degradation were 53.91% and 16.11%, respectively. Specifically, Cl·, ClO·, and Cl2·− were responsible for 8.59%, 2.69%, and 4.83% of RBV removal. The RBV degradation pathway indicated that the reactive species preferentially attacked the amide moiety of RBV, which cleaved the ether bond and the hydroxyl group. The toxicity evaluation of RBV degradation products elucidated that UV/chlorine/Fe(II) process was beneficial for RBV detoxification.

Efficient water disinfection with ball milled Mg-biochar: The key role of trace Cu

In this study, magnesium and coconut shell carbon (CSC) were prepared by a ball milled process and used for water disinfection with adsorbing tiny amounts of copper(II). Dissolved oxygen (DO) was reduced to hydrogen peroxide (H_(2)O_(2)) via a two-electron pathway by Mg corrosion. Cu(II) in the wastewater will be enriched on the CSC surface and efficiently catalyzes H2O2 for inactivating E. coli. The results show that E. coli with an initial concentration of approximately 106 CFU/mL was under the detection limit (<4 CFU/mL) within 15 min. All of the Cu(II) could be adsorbed by the composite and catalyzed H2O2 to different active species. The quenching experiments, electron spin resonance (ESR) capture measurements and the UV-vis spectroscopy detection confirmed the present of the hydroxyl radicals (·OH), superoxide radicals (·O_(2)^(-)) and Cu(III). Different with tradition Fenton like process, Cu(III), rather than radicals, played the major role during the Mg-CSC/Cu(II) process. In addition to the cellular membrane damage, most of the bacterial genomic DNA was also be degraded and the bacterial reactivation was avoided. The Mg-CSC/Cu(II) process also showed a satisfied disinfection performance in real wastewater treatment. Overall, this study provides a new strategy for water disinfection.
