Hierarchical Mesoporous SSZ-13 Chabazite Zeolites for Carbon Dioxide Capture

Artificial carbon dioxide capture is an alternative method to remove the already accumulated in atmosphere as well stop its release at large-scale emission points source, such power plants. However, new adsorbents are needed make approach feasible. For this purpose, study, hierarchical mesoporous-microporous chabazite-type zeolites were synthesised by applying a dual-templating method. The microporous zeolite structure-directing agent N,N,N-trimethyl-1-adamantanammonium hydroxide was combined with organosilane mesopore-generating template, 3-(trimethoxysilyl)propyl octadecyl dimethyl ammonium chloride. Materials characterised for their structural and textural properties tested capacity both original sodium form proton-exchanged means of breakthrough curve analysis sorption isotherms. influence template ratios on structure, capture, have been identified. All mesoporous materials showed fast adsorption-desorption kinetics due reduction steric limitations via introduction meso range network pores. recyclable negligible loss crystallinity capacity, which makes them potential larger-scale application.
