UV-assisted one-pot synthesis of bimetallic Ag-Pt decorated reduced graphene oxide for colorimetric determination of hydrogen peroxide |

Composite |
The nanocomposites were prepared through a one-pot reduction of potassium
chloroplatinate, silver nitrate, and graphene oxide under ultraviolet irradiation without using any extra chemical reducing agents
or surfactants. The successful formation of Ag-Pt/rGO nanocomposites was confirmed by transmission electron microscopy,
energy disperse spectroscopy mapping, X-ray photoelectron spectroscopy, and X-ray diffraction analysis. Significantly, Ag-Pt/
rGO nanocomposites possessed excellent peroxidase-like activity toward the catalytic oxidation of 3,3′,5,5′-tetramethylbenzidine
to form a blue product in the presence of hydrogen peroxide. |
