New Insights into the Role of the Hydrothermal Conditions for the Synthesis of Open-Framework Fluorinated Gallium Phosphates

摘要

This contribution deals with the synthesis of fluorinated gallium phosphates of the ULM-n series (ULM-3 adn ULM-4) followed by in situ X-ray diffraction techniques using synchrotron radiation. In specific conditions, some intermediate phases appear before the formation of ULM-3 and room temperature synthese have been performed in order to isolate the compounds produced at very short reaction time. This work revealed that 1D solid is obtained at low temperature and its transformation into 3D framework ULM-3 was studied.
