Because of this, in particular, the soft-template strategy strongly depends on the experimental conditions used (e.g., pH, temperature, solvent, ionic strength, etc.). Lastly, self-templating synthesis generally depends on specific formulations and conditions and is classified into three sub-categories according to the nature of the target material: (i) inorganic and metallic particles, (ii) polymer particles, and (iii) small organic particles . Table presents a variety of morphologies obtained from spherical materials and hollow structures prepared by conventional and unconventional hydro(solvo)thermal synthesis.
