Synthesis And Characterisation Of Colloidal Alpo-S Nanocrystals Templated By L-Ethyl-2,3- Dimetiiylimidazolium Hydroxide

Colloidal stable nanosized AIPO-S crystals were synthesised via hydrothermal method using a new template, l-ethyl-2,3-dimethylimidazolium hydroxide, [edmim]OH. The syntheses were carried out under various synthesis conditions such as heating time, heating temperature and molar composition of pre...
