“…It is known that zinc oxide (ZnO) is a promising multifunctional compound broadly utilized in many applications [ 1 , 2 , 3 , 4 , 5 ]. ZnO is used in optoelectronics [ 6 , 7 ], agriculture [ 8 ], wastewater treatment [ 9 , 10 , 11 ] and catalysis [ 12 , 13 ] as a vulcanization activator for rubbers, a hardener or a crosslinking agent for elastomers [ 14 , 15 ], and in the production of electrically conductive carbon materials [ 16 ]; it is also used in the cosmetics, medicine and biotechnology industries [ 17 , 18 , 19 , 20 , 21 ], including its use in the elaboration of biodegradable antibacterial packaging [ 22 , 23 ], and photovoltaic solar cells for “green” energy [ 24 , 25 ].…”
