Green Synthesis of Noble Nanometals (Au, Pt, Pd) Using Glycerol under Microwave Irradiation Conditions

A newer application of glycerol in the field of nanomaterials synthesis has been developed from both the economic and environmental points of view. Glycerol can act as a reducing agent for the fabrication of noble nanometals, such as Au, Pt, and Pd, under microwave irradiation. Their shapes can be changed by adding different surfactants. In the presence of CTAB, Au nanosheets were formed within 2 min where the size of Au nanosheets can be controlled by the microwave irradiation time and glycerol content.
