To achieve high electrooxidation efficiency for phenol, this study explored the fabrication of Mn-MIL-100 catalysts at various calcination temperatures, loaded onto a carbon paper (CP) anode. The materials were characterized using scanning electron micros-copy, X-ray photoelectron spectroscopy, thermogravimetric analysis, and diffraction. Their electrocatalytic activities under temperatures evaluated through cyclic voltammetry (CV) tests, while effect pH in Mn-MOF modified CP electrodes on phenol degradation performance was investigated potentiostatic discharge method. Mn-MOF@CP calcined 400 °C 500 (denoted as Mn400@CP Mn500@CP, respectively) exhibited significantly enhanced current responses solution, attributed to an increase oxygen vacancy concentration. A 96.00 ± 1.53% achieved by within 16 h, it only 60.12 2.03% Mn500@CP 8.01 2.00% blank 4. Additionally, consistently demonstrated superior over across values. outstanding activity oxidation could be its lower charge transfer resistance. radical-mediated pathway proposed system, elucidating mechanism. These findings highlighted potential Mn-MOF-derived carbon-based organic contaminants.
