Hydrothermal Formation of the Head-to-Head Coalesced Szaibelyite MgBO(2)(OH) Nanowires.
The significant effect of the feeding mode on the morphology and size distribution of the hydrothermal synthesized MgBO(2)(OH) is investigated, which indicates that, slow dropping rate (0.5 drop s(-1)) and small droplet size (0.02 mL d(-1)) of the dropwise added NaOH solution are favorable for promoting the one-dimensional (1D) preferential growth and thus enlarging the aspect ratio of the 1D MgBO(2)(OH) nanostructures. The joint effect of the low concentration of the reactants and feeding mode on the hydrothermal product results in the head-to-head coalesced MgBO(2)(OH) nanowires with a length of 0.5-9.0 mum, a diameter of 20-70 nm, and an aspect ratio of 20-300 in absence of any capping reagents/surfactants or seeds.
