a EPR analysis for O2•– detection with 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) as a trapping agent. b EPR analysis for 1O2 detection with 2,2,6,6-tetramethyl-4-piperidinol (TEMP) as a trapping agent. c ROS production. d PhOH degradation processes in the Cu@GC-Al2O3/O3 system. e Relative energy profile of the proposed intermediates and transition state (TS) in the interaction of O3 and the Cu1–C3 or the Cun–Cun. f Relative energy profile of the proposed intermediates and TS in the interaction of O3 and the Cu1–C3–*Oad or Cun–Cun–*Oad. g The mechanism of Cu@GC-Al2O3/O3 reaction. The error bars in (c, d) represent the standard deviations of triplicate tests. Source data are provided as a Source Data file.
