文摘
- •
Seeded growth led to the synthesis of mono-disperse, diamond-like DDR particles.
- •
Change of the seed amount allowed for the control of the size of all silica DDR particles.
- •
High CO2/N2 sorption and permeation selectivities were observed for DDR zeolites.
- •
Water adsorption depends on defects and strongly on Al constituents in DDR zeolites.
