文摘
- •
Nanohybrid SWCNHs/CeO2 materials fully characterized and successfully used as electrocatalysts in the sensing of H2O2.
- •
Synergistic effect between the CeO2 layer and the nano-carbon support strongly depending on their contact.
- •
The sensitivity of the sensor (160 ± 20 μA cm−2 mM−1) is two orders of magnitude higher than the corresponding pristine materials alone.
- •
The sensor is suitable for real sample sensing applications.
