“…3d, T(Au x P) 8 exhibits the smallest semicircle arc radius compared with T(Ag x P) 8 , T(Au 25 P) 8 , TP 8 , and TNTAs, implying its most efficient interfacial charge separation efficiency. 21,49 As summarized in Table S3, † T(Au x P) 8 demonstrates the lowest charge transfer resistance (3290 U) with respect to other photoelectrodes, that is, T(Ag x P) 8 (3375 U), T(Au 25 P) 8 (4233 U), TP 8 (11 170 U), and TNTAs (11 510 U), implying that cooperativity of Au x NCs and PAH is advantageous to boost the interfacial charge transport efficiency. The results are consistent with the LSV and I-t results.…”
