Ethyl methyl carbonate (EMC) is a crucial solvent extensively utilized in lithium-ion battery electrolytes; the transesterification of dimethyl carbonate (DMC) with ethanol is a pivotal reaction for EMC production. However, this reaction faces challenges due to the trade-off between catalytic activity and selectivity from the basic catalysts. In this issue, we report an innovative strategy through fine-tuning the electron-donor capability of the basic phenolate anion ([PhO]) in a novel poly(ionic liquid) (PIL) framework, as synthesized via an alkylation reaction between 1,3,5-tris(bromomethyl)benzene, biphenyldiimidazole, and N,N′-carbonyldiimidazole (CDI) to trigger targeted basicity that can directionally catalyze the transesterification of DMC with ethanol, so as to achieve both ultrahigh catalytic activity and selectivity toward EMC. By varying the substituent groups with electron-withdrawing and electron-donating effects on the phenolate anion, the PILs show expected changes in the catalytic performance, following well with the trend of charge density on these substituted phenolate anions. The optimized catalyst [CPIL-CDI][MeOPhO], induced by p-methoxyphenolate anions, allows an extraordinary EMC yield of 72.19% and an EMC selectivity of 91.48% under mild conditions without any process intensifications, suppressing all of the reported catalysts reported to date. Outcomes and approaches shown in this work have the potential to expedite the systematic design of cations and anions within PILs for industrial-scale EMC production through environmentally friendly transesterification processes.

“…Such doping can change the crystal structure and lattice defects and add more active sites, boosting electrocatalytic activity and reaction surface area of the electrode. [26][27][28][29] For example, Dai's study demonstrated that nickel doping in the PbO 2 anode can improve the electrocatalytic degradation of difficult-to-degrade organic pollutants, and compared with lead oxide anode, Ni-PbO 2 showed a 1.22-fold growth in COD removal and 1.20-fold growth in total organic carbon (TOC) removal, respectively. 30 Feng et al improved the electrocatalytic performance by preparing NCNSs-PbO 2 .…”

A three-dimensional porous lead dioxide electrode (3D-PbO2) was developed by the template electrodeposition approach. Polystyrene microspheres were prepared by microemulsion polymerization, and then the polystyrene template was loaded on the PbO2 electrode by electrodeposition. Finally, a porous structure was formed by removing the template. Under these optimized conditions, the degradation of acyclovir could achieve complete removal, while the removal of COD was 29.59%. The electrochemical degradation process of acyclovir was consistent with the proposed primary reaction kinetics. The 3D-PbO2 electrode was comprehensively characterized using scanning electron microscopy S(EM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) techniques. The SEM analysis revealed the presence of well-defined porous structures on the electrode surface, while the XRD results indicated a reduction in electrode crystal sizes. Additionally, the XPS analysis demonstrated a higher proportion of reactive oxygen species on the 3D-PbO2 electrode. The electrochemical properties of the electrode were investigated using CV and EIS. The experimental findings demonstrate that the 3D-PbO2 electrode exhibits a higher oxygen evolution potential and lower charge transfer resistance than the conventional PbO2 electrode. This study presents a viable approach to enhance the electrochemical oxidation performance of lead dioxide.
