“…Good electrodes should be not only effective for pollutant degradation, but also stable electrochemically. Up to date, numerous types of electrodes including Pt [1], graphite [2,3], PbO 2 [4][5][6][7][8], SnO 2 [7,[9][10][11], IrO 2 [11][12][13], Pt-Ir [14], RuO 2 [15], glassy carbon [16], fiber carbon [17], MnO 2 [18,19], TiO 2 [20,21], and boron-doped diamond (BDD) have been investigated. SnO 2 electrodes are generally believed to be superior to Pt, graphite, PbO 2 , and many other common electrodes.…”
