摘要

This study investigates the synthesis of zinc oxide powders for microwave dielectric applications using deep eutectic solvents. Depending on the solvent employed, single-phase ZnO powders were obtained, with particle size and phase composition controlled by varying the calcination temperature. Deep eutectic solvents enable the preparation of zinc oxide precursors through interaction with water. The approach is environmentally benign, since no alkalis or ammonium hydroxide are required. Nanoparticles produced at 500°C exhibited pronounced antimicrobial activity against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli).
