“…Up to now, several kinds of catalytic materials for CEs, such as platinum [5][6][7][8][9][10][11], carbon materials (graphite, activated carbon, carbon black, single-wall carbon nanotubes) [12][13][14][15][16][17], poly(3,4-ethylenedioxythiophene) (PEDOT) [18][19][20][21][22], poly(3,3-diethyl-3,4-dihydro-2H-thieno- [3,4-b] [1,4]dioxepine) (PProDOTEt 2 ) [23], polypyrrole [24] and polyaniline [25], have been introduced. However, the best candidate for the CE is Pt due to its highly catalytic effect toward triiodide reaction, superior chemical and electrochemical stabilities.…”
