In this work, various new-observed structured CeCO3OH were synthesized by a self-assembly hydrothermal method, and a novel tactic to produce CeO2-x with excellent photocatalytic activity by decomposing CeCO3OH in H2 was proposed and identified. By controlling the synthetic conditions, almond-like,...
The as-synthesized CeCO 3OH has uniform lengths and good dispersion. Synthetic parameters, such as the concentration of reagents, were found to have close relationship with the morphologies and sizes of the final products. The ultrasound-induced oriented attachment growth mechanism has been proposed ...
