6-Aza-2-thio-thymine-gold nanoclusters: an excellent candidate in the photoelectrochemical field

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 mu A cm(-2) with O-2 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.

Automated summary

Research has shown that using 6-aza-2-thio-thymine-AuNCs (ATT-AuNCs) as a photoactive material can achieve high performance in photoelectrochemical properties, with characteristics such as higher cathodic photocurrent density and carrier density compared to other AuNCs.
