Gas–Liquid Cold Plasma for Synthesizing Copper Hydroxide Nitrate Nanosheets with High Adsorption Capacity

Abstract

A facile, fast and environmentally friendly gas–liquid plasma method for synthesizing Cu2(OH)3NO3 nanosheets is reported for the first time. The preparation process just takes 12 min using Cu(NO3)2 aqueous solution without any other chemical agents. The Cu2(OH)3NO3 nanosheets exhibit much higher methyl orange (MO) adsorption capacity (428.8 mg MO g−1) than that prepared by the solvothermal method (212.8 mg MO g−1).
