A High Voltage Sonoelectrochemical Route for Preparation of Highly Oxidized Carbon Nanosheets with Excellent Electrocatalytic Property

A high voltage sonoelectrochemical method was proposed for the preparation of highly oxidized carbon nanosheets (hoCNSs) with good hydrophilicity and excellent electrocatalytic property for various compounds. It was found that the high electrolytic voltage played an important role in the hoCNSs' fragmentary appearance and excellent electrocatalytic property. The ultrasonic power further obviously improved the electrolytic efficiency. The very low concentration of electrolyte leads to a very simple post-treatment process. So this facile, low-cost and environmentally friendly method had great utility value for the preparation of hoCNSs.
