摘要
The high performance of the photoelectrochemical (PEC) properties of AuNCs can be achieved with 6-aza-2-thio-thymine-AuNCs (ATT-AuNCs) as a photoactive material. The ATT-AuNCs yielded a cathodic photocurrent density as high as 88 μA cm-2 with O2 as electron acceptor, which is three orders of magnitude higher than those of other AuNCs in aqueous solutions. Moreover, ATT-AuNCs also show a higher carrier density, shorter Debye length, and smaller depletion layer width than those of reported AuNCs. This work not only reveals the PEC performance and mechanism of ATT-AuNCs, but also establishes a framework for in-depth design and studying the PEC performance of AuNCs.
