文摘
- •
Montmorillonite (MMT)-supported CuS nanoparticles was synthesized by a facile one-step method.
- •
CuS-MMT nanocomposites were for the first time demonstrated to possess the excellent intrinsic peroxidase-like activity.
- •
CuS-MMT nanocomposites showed highly catalytic activity in a very short time.
- •
A sensitive colorimetric sensor for H2O2 is fabricated based on the CuS-MMT nanocomposites.
- •
The catalytic mechanism is due to the generation of hydroxyl radical (
OH) decomposed from H2O2.
