In order to control particle size and the distribution, Co-Al layered double hydroxides were prepared from aqueous glycerol solutions of cobalt chloride and aluminum chloride by urea hydrolysis under hydrothermal conditions. Effects of the synthetic conditions including heating temperature and time, and glycerol/water ratio on the particle size and its distributions of Co-Al layered double hydroxide were discussed. Particle diameter was controlled from 1.0 (glycerol/water ratio = 10 g/40 mL) to 38.3 μm (glycerol/water ratio = 0 g/40 mL, heating at 50 °C for 150 days). Narrow particle diameter distribution as low as 20% coefficient of variation was achieved under optimized synthetic conditions (glycerol/water ratio = 10 g/40 mL, heating temperature < 80 °C).
