摘要：
The detection of hydrogen peroxide (H2O2) has considerable significance in industrial application and pathological monitoring. Inspired by the attributes of functional mesoporous carbons, a non-enzymatic sensor was constructed based on AgNPs doping carbon nanoflower composites (AgNPs/CNF). The characterization results showed that AgNPs/CNF with nanoflower structure greatly enhanced electron transfer rate and displayed outstanding catalytic performance for H2O2. Remarkably, the prepared sensor presented super low detection limit (5.83 x 10-11 M) and the wider detection range (1.75 x 10-10 - 5.41 x 10-3 M). In addition, the content of H2O2 in the actual disinfectant and human serum samples were further detected, and the recover ratios were 96.00 % - 104.0 % and 96.00-105.2 %, respectively, indicating the prepared sensor can detect H2O2 effectively.
