Abstract
Constructing mesoporous single crystals is largely limited due to the challenge of controlling the assembly of nanocrystal building blocks
via
a conventional evaporation-induced self-assembly process. Here, we developed a facile synergistically controlled evaporation and hydrolysis method to prepare mesoporous single crystal NiO nanorod arrays. The crystallinity of mesoporous NiO is readily tuned from polycrystalline to single crystalline by controlling the evaporation and hydrolysis rates of precursor solvents.
Mesoporous single-crystal NiO was synthesized by controlling metal ion hydrolysis and solvent evaporation rates, exhibiting excellent electrochemical activities.
