A detailed investigation of electrochemical hydrodefluorination of 4-fluo-rophenol: Rh-doped cathode preparation, reaction conditions optimizations, reactive species identification, and in situ characterization

Jiaxin Zhu et al.

Summary: The discharge of widely used fluorinated aromatics (FAs) leads to their notoriously high persistence and toxicity in natural environments. Defluorination is the key step for FAs pollutants detoxification. In this study, 4-fluorophenol (4-FP) was selected as a model compound to optimize the electrochemical hydrodefluorination (HDF) process and understand the reaction mechanism. The investigation showed that Rh coating outperformed Pd coating due to its higher reactivity towards C-F bond cleavage.

Shitai Shen et al.

Summary: This study investigated the mechanism of manganese oxide with different crystallographic structures in activating persulfate, revealing that surface-bound PMS complexes and direct oxidation by surface manganese species are the dominant oxidation mechanisms for ACE degradation. Furthermore, the catalytic activity of MnO2 was positively correlated with the content of MnIII(s) on the catalyst surface, which stimulated the generation of more oxygen vacancies beneficial for PMS adsorption and the formation of reactive complexes.
