摘要：

A simple and green method for preparation of Au nanoparticles by reduction of HAuCl4 using carbon nanodots as the reducing agent is reported. The carbon nanodots were prepared by a green method as well, using hydrothermal treatment of grass. It is observed that Au nanoparticles show obvious electrochemical catalytic ability for reduction of hydrogen peroxide, leading to its application of a high-performance non-enzymatic hydrogen peroxide sensor. The hydrogen peroxide sensor based on Au nanoparticles was made, with the detection limit at 23 mu M and linear range between 0.1-160 mM.
