Gold particles decorated reduced graphene oxide for low level mercury vapor detection with rapid response at room temperature

Rapid and sensitive detection of mercury vapor is of great significance for environmental protection and human health. But the detection method enabling low detection limitation and rapid response at room temperature simultaneously has rarely been reported. In this work, we propose a gold particles...

After adding the gold particles, the reduced graphene oxide sensors’ response sensitivity increase by more than 16 times and the response time significantly decreases, which is far less below the results reported by others.
