文摘
- •
AgNPs selectively deposited and uniformly covered on the Gr-CCS as a novel modified electrode material to build H2O2 sensors.
- •
Gr-CCS-AgNPs/GCE was utilized first as a new sensor for determination of H2O2.
- •
The sensor has many advantages such as easy preparation, low limit of detection and excellent selectivity.
