摘要：
Ag nanoparticles-decorated reduced graphene oxide (AgNPs-rGO) has been successfully fabricated through a one-step strategy, carried out by hydrothermal treatment of the mixture of AgNO3 and GO solution under strong alkaline conditions at 180 degrees C for 30 min. The reaction was accomplished without extra reducing agent and surface modifier. As-synthesized AgNPs-rGO has been successfully applied in catalytic performance toward the reduction of H2O2. This H2O2 sensor shows a wide linear range of 0.1-60 mM (r=0.991) and a low detection limit of 1.80 mu M at a signal-to-noise ratio of 3. (C) 2012 Elsevier Ltd. All rights reserved.
