Composites ZSM-5/KIT-6 Synthesized Via Assembly Modification Procedure and Mechanical Grinding Procedure, Respectively, and Their Application to CO2 Adsorption

An amine-bifunctionalization strategy with Beta/KIT-6 composite as a support for CO2 adsorbent preparation

“…5a and b, KIT-6, BK, A-BK-1 belonged to the type IV isotherm, showing the type H1 hysteresis ring, which conformed to the adsorption characteristics of mesoporous structure. 44 Beta belonged to the type I isotherm, which was the adsorption characteristic curve of microporous materials. The hysteresis loop height of KIT-6 was higher than that of BK, indicating that its pore volume was larger than that of BK.…”

Carbon dioxide capture with zeotype materials

“…Furthermore, Lin et al demonstrated that synthesis of a micro–mesoporous composite is the key to the superior performance of the material. 165 The composite synthesized from assembly procedure can adsorb 1.22 mmol CO 2 g −1 composite (15 kPa, 60 °C), which is much higher than the capacities from either the 0.92 mmol g −1 for ZSM-5 or 0.82 mmol g −1 for KIT-6. Importantly, they found that physical mixture of the two components could not realize the same capacity as obtained from the synthesized composite.…”

“…161,162 These drawbacks may be lessened by introducing another material component (Fig. 10) such as MOFs, 159,163,164 mesoporous materials, 160,161,165 and second zeolites, 166 etc. It is expected that the zeolite composites have combined advantages of two structures.…”

“…It is the desire of these composites to have synergistic performance rather than additive of individual characteristics from the two components. 165…”
