a 4-CP degradation curves of different samples. b, Quenching experiments of the Fe/CN + PI and the Fe/SCN + PI systems (the error bars in a and b are all standard deviations calculated from the results of three parallel experiments). c EPR signals of 1O2 and ·O2- in the Fe/SCN + PI system. d EPR signals of 1O2 in different system. e EPR spectrum of DMPO adducts in the Fe/SCN + PI system. f Correlation between 4-CP degradation and PI consumption in the Fe/SCN + PI system. g, h Chronoamperometry (g) and chronopotentiometry (h) curves of different catalysts.
