The carbamoylphosphosphonatesilane(CMPO) analogue;2-(diphenylphosphoryl)-N-(3-(triethoxysilylpropyl)acetamide) modified mesoporous silica was prepared via a post-synthesis grafting method for the effective purification of rare earth elements. The guest CMPO analogue was synthesized by direct coupling reaction of 2-(diphenylphosphoryl)acetic acid and 3-(triethoxysilyl)propan-1-amine. Various mesoporous silicas such as MCM-41, SBA-15, or amorphous silica nano particles were adopted as host materials. The resulting surface modified mesoporous materials were characterized with respect to their structural integrity, surface area, pore size and the concentration of the CMPO silanespecies. These CMPO functionalized periodic mesostructured silicates offer the potential of applications as catalysts, sensors, or environmental sorbents. Details of characterization (SAXS, IR, N2 adsorption-desorption isotherm, TEM, SEM, TG-DTA) are summarized.
