Single-Nanometer-Sized Low-Valence Metal Hydroxide Crystals: Synthesis via Epoxide-Mediated Alkalinization and Assembly toward Functional Mesoporous Materials
A study demonstrated a simple synthesis approach toward single-nanometer-sized crystals that work as nanobuilding blocks (NBBs) to form a great variety of mesoporous hydroxides and derived phases. The nanocrystals with diverse chemical compositions low-valence metal hydroxides, α-M(OH)2 (M = Mn(II),...
