PtPd nanodendrites supported on graphene nanosheets: A peroxidase-like catalyst for colorimetric detection of H2O2

- A simple and green method to prepare well-dispersed PtPd nanodendrites on graphene nanosheets (PtPdNDs/GNs).
- The enzyme mimic behavior of as-prepared PtPdNDs/GNs showed high peroxidase-like catalytic activity.
- A colorimetric sensing strategy for H2O2 was developed based on the PtPdNDs/GNs catalyst.
