Polyvinyl chloride (PVC), one of the most extensively produced polymers, has raised significant environment and public health concerns due to its persistence in ecosystem, long-term accumulation associated toxicity. The well-established mechanical recycling approach for treating waste PVC often result polymer degradation release hazardous by-products, such as corrosive HCl. We envisage that tandem with a halogenation reaction provide new solution management. Herein, we demonstrated plastic could serve chlorination reagents, combination triboelectric catalyst, achieve efficient alcohols under ball milling condition. TiO2, mediates single electron transfer process promotes dehydrochlorination PVC, thereby enabling in-situ alcohols. This strategy was applicable variety aliphatic benzylic alcohols, yielding corresponding organic chlorides moderate excellent yields. In particular, yield benzyl reached 95% after 4 h milling.

Overall, this method provides inspiration using chlorine source initiate chemical reactions through approaches.

Abstract The thermal treatment method is a leading approach for enhancing the insufficient electrochemical activity of graphite felts (GFs) as electrodes in iron‐chromium redox flow batteries (ICRFBs). Therefore, design parameters plays crucial role thermally‐treated GFs (TGFs), considered one most effective ways to mitigate polarization, ohmic and concentration polarization ICRFBs. In paper, TGFs were determined be 500 °C 15 h at sample density 0.5 g/L. reaction processes occurring on surface decoupled quantified into capacitance values determine their correlation with cell performance. essence area, oxygen functional groups, fiber substrate was further investigated. fact, presence groups can enhance electrolyte adsorption C─O being improving rate. Additionally, carbon structure area have significant impact core electron delivery component This study provides comprehensive assessment influence performance, while also establishing theoretical foundation development modification specific other system.
