文摘
- •
The carbon quantum dots (CQDs) synthesized with PEI showed an extraordinary reducibility.
- •
The Ag/CQDs composite was prepared by using CQDs as reducing and stabilizing agent.
- •
A simple Ag/CQDs composite-based dual-signal probe was provided for Hg2+ detection.
- •
The proposed strategy shows a potential for detecting Hg2+ in real water samples.
