Nanomaterials 2021, 11, 238 2 of 12 Recently, an additional mechanism for the synthesis of ZnO was suggested [25]—a solid-state phase transformation: "-Zn(OH)2 (s) ! ZnO (s) + H2O It was shown that even without the solvation of "-Zn(OH)2, the phase transforma- tion is possible by heating to relatively low temperature [25], and that with solvation of
