dc.description.abstract | Nitrogen-enriched two-dimensional (2D) porous polybenzimidazole (2D-HPBI) network was synthesized from the reaction between 1,2,4,5-tetraaminobenzene (TAB) and benzene-1,3,5-tricarboxylic acid (BTA) in polyphosphoric acid (PPA) medium. Interestingly, the remnant terminal groups such as amine and carboxyl groups at the periphery of 2D-HPBI were selectively stripped off by heat-treatment at 470 °C. The resultant heat-treated 2D-HPBI (HT-HPBI) displayed substantially improved electrical conductivity and thus outstanding performance as the counter electrode (CE) for the cobalt reduction reaction (CRR) in dye-sensitized solar cells (DSSCs). The charge-transfer resistance (Rct=0.51 Ω cm2) at the HT-HPBI-CE/electrolyte interface was even lower than that of Pt-CE (1.09 Ω cm2). More importantly, HT-HPBI-based CE showed near “zero” loss of electrochemical stability (1/Rct) even after 1000 potential cycles, while the 1/Rct of Pt decreased to <10% that of a fresh cell. | - |
