Tetrapod-like CuCl crystallites with uniform sizes were generated conveniently in a mixed solution of acetylacetone and ethylene glycol at 120 °C under solvothermal conditions. The products were characterized by XRD, XPS, SEM, UV–Vis and PL techniques. The average length of the legs of T-CuCl is 30 µm. The morphologies of the products were related to the reaction temperature, time and the volume ratio of the solvents. A solvent-mediated morphological transformation mechanism was proposed and it was in good agreement with the observations made with scanning electron microscopy. The role of the two solvents was also explored.

Anatase TiO₂, hexagonal Nd₂O₃, amorphous SiO₂ and Al₂O₃ with macroporous or hollow sphere structures have been fabricated by employing periodically macroporous active carbon as a template; the final morphology of the oxides can be controlled by the number of infiltration steps and the addition of solvent to the precursor.
