Summary: Based on two different topologies of MOFs, core-shell bimetallic MIL-101/ZIF-67(x) (M/Z(x)) materials were successfully synthesized for the activation of peroxymonosulfate (PMS) self-decomposition in order to degrade 2-chlorophenol. The M/Z(x) exhibited not only the advantages of single-metal MOFs such as high surface area and pore volume, but also superior catalytic performance. Further investigation revealed that the catalytic degradation of 2-chlorophenol was promoted by the synergistic effect of cobalt and iron active sites in M/Z(x), which enhanced the Co2+/Co3+ redox cycle. Radical and non-radical pathways contributed to the degradation, with singlet oxygen (O-1(2)) playing a predominant role in the non-radical pathway. Sulfate radical (SO4 center dot-) and hydroxyl radical ((OH)-O-center dot) also accelerated the degradation process.

Summary: The study demonstrates that iron oxide/titania heterostructures exhibit efficient removal of AsH3 under UV light, with good humidity stability and water resistance. The superior room temperature catalytic activity for AsH3 removal can be attributed to the light-induced formation of highly active oxygen species and enhanced desorption of adsorbed water.

Summary: Mercury pollution, primarily from coal combustion, poses a serious threat to both human health and ecosystems. A magnetic material, CTF, was developed to enhance the removal of elemental mercury (Hg-0) during chemical-looping combustion of coal (CLCC). Results showed that CTF promoted the conversion of Hg-0 to Hg2+/HgP in the presence of HCl, contributing to a higher mercury removal efficiency.

Summary: Fuel cells have attracted widespread attention as an alternative to fossil energy due to their high conversion efficiency and low pollution emissions. The development of fuel cells relies heavily on cathodic ORR catalysts with excellent performance and cost-effectiveness. In this study, a Pd@PtRuNi core-shell bilayer nanostructure was constructed using Pd NWs as a template to enhance platinum atom utilization. The Pd@PtRuNi bilayer core-shell NWs exhibited significantly higher mass activity compared to pristine Pd NWs and benchmark commercial Pt/C. The enhanced catalytic properties can be attributed to the synergism between the ligand effect of Ni and Ru and the one-dimensional structure superiority.

Summary: This study explored the significantly accelerated defluorination of recalcitrant perfluorooctanoic acid (PFOA) with the co-present nitrate by UV/sulfite treatment. The deep defluorination of PFOA and complete denitrification of nitrate were simultaneously achieved in the UV/sulfite-nitrate system. It was found that reactive nitrogen species (RNS) played significant roles in the promoted defluorination apart from reductive defluorination. The results highlight the importance of the UV/sulfite-nitrate system for the remediation of perfluorinated compound contaminated water.

Summary: Oxyanion-modified zerovalent iron (OM-ZVI) materials have attracted attention in pollutant removal due to their synthesis methods, characterization techniques, and enhanced performance. Phosphate modification forms iron-phosphate facilitating Cr(vi) removal, oxalate modification increases electron cloud density and surface-bound Fe(ii) for Cr(vi) removal, and mechanochemical treatment with B2O3 promotes electron transfer for Cr(vi) reduction. OM-ZVI shows potential for pollution control and environmental remediation.

Summary: This study demonstrates that surface phosphorylation can greatly enhance the O2 photoactivation of BiOBr, leading to a higher generation rate of superoxide radicals. The phosphorylated BiOBr surface establishes an interfacial electrostatic field, weakens the surface Bi-O bonds, and induces oxygen vacancy (VO) generation, facilitating exciton dissociation and the activation of absorbed O2. This surface phosphorylated BiOBr shows a significantly higher degradation rate of chlorobenzene solution and is able to decrease the COD value of industrial chlorobenzene wastewater below the water quality standards.

Summary: High-valent metal-oxo species, such as Co-IV=O, are effective non-radical reactive species for advanced oxidation processes (AOPs) to degrade water pollutants. However, generating Co-IV=O in peroxymonosulfate (PMS)-based AOPs is challenging. In this study, a strategy to construct isolated Co sites with unique N1O2 coordination on the Mn3O4 surface was proposed. The resulting CoN1O2/Mn3O4 catalyst showed high activity in PMS activation and sulfamethoxazole degradation, outperforming other catalysts. Co-IV=O species efficiently oxidized contaminants via oxygen atom transfer. These findings contribute to the understanding of PMS activation mechanism and the design of efficient environmental catalysts.

Summary: The mechanistic study of soil and groundwater remediation in petroleum contaminated lands requires rapid qualitative and quantitative identification of petroleum substances. In this study, a strategy using dual-excitation Raman spectroscopy and microscopy was developed for on-site detection and in-situ monitoring of petroleum compositions and contents in soil and groundwater. The method provided detection times of 0.5 hours and one minute, and detection limits of 94 ppm and 0.46 ppm for soil and groundwater samples, respectively. Raman microscopy revealed the petroleum changes at the soil-groundwater interface during the remediation processes. This method can shed light on the petroleum degradation mechanism and facilitate the selection of suitable remediation plans.

Summary: This study investigates the removal performance of NH4+-N in the presence of co-existing halogenated phenol using waste lithium-ion batteries (LIBs) material-derived catalysts activating peroxymonosulfate system (LIBs/PMS). The results show that TCP can degrade rapidly within 2 minutes, regardless of the presence of NH4+-N. Interestingly, NH4+-N removal is initiated by TCP and is strongly dependent on TCP dechlorination. Moreover, NH4+-N removal is thermally accelerated in the temperature range of 25 to 60 degrees C.
