adsorption - 2025 NAFTA

Packet 1: Bonus 18

Answer some questions about using metal-organic frameworks as carbon capture agents, for 10 points each.

[10m] The small pore sizes and low heat capacities of MOFs allow them to capture carbon via this process. Saturated MOFs can be regenerated with either the “temperature-swing” or “pressure-swing” forms of this process.

ANSWER: adsorption [accept temperature-swing adsorption or pressure-swing adsorption; reject “absorption”]

[10h] Due to their hydrophobic nature, this class of “glassy” MOFs are useful for carbon capture. Chemical “caryatids” improve the stability of these MOFs, which are topologically isomorphic to zeolites.

ANSWER: zeolitic imidazolate frameworks [or ZIFs]

[10e] MOFs can catalyze the conversion of CO2 to biogas when coordinated with elements from this series, which are above actinides on the periodic table.

ANSWER: lanthanides [prompt on rare-earth elements]
