WebOct 16, 2024 · The synthesis of nanosized CHA‐type zeolite without organic structure‐directing agents is presented. The zeolite material exhibits excellent CO2 … WebThe synthesis of CHA from FAU (2.6) zeolite is based on the procedure reported by Bourgogne et al.36 with modifications to the synthesis composition. NaOH (40 wt% in water), KOH (45 wt% in water), and water were mixed in a polypropylene container (PP, Nalgene) before FAU (2.6) was added to the container. richard wernick composer
