Abstract:
DDR nanocrystals were synthesized using hydrothermal secondary growth. The morphology of the nanoparticles can be manipulated by changing the ratio of silica to water, the synthesis temperature, and the mineralizing agents. Specifically, nanocrystals with morphology of hexagonal plates, octahedral, and diamond-like plates are disclosed. These nanoparticles can be used as seed coatings for DDR membrane growth on substrates, and for the fabrication of mixed matrix membranes, and for any other use where uniform, small DDR zeolite crystals are beneficial.
