Metal-Organic Framework Adsorbent for Practical Capture of Trace Carbon Dioxide.

Control of indoor CO concentration to a safe level is important to human health. Metal-organic-framework-based adsorbents show superior adsorption performance at moderate CO concentration compared to other solid adsorbents but suffer from low capacities and high regeneration temperature at indoor CO concentrations and poor humidity stability. Herein, we report epn-grafted Mg(dobpdc) (epn = 1-ethylpropane-1,3-diamine) showing a CO capacity of 12.

A Hydrogen-Bonded Organic Framework (HOF) with Type IV NH Adsorption Behavior.

An S-shaped gas isotherm pattern displays high working capacity in pressure-swing adsorption cycle, as established for CO , CH , acetylene, and CO. However, to our knowledge, this type of adsorption behavior has not been revealed for NH gas. Herein, we design and characterize a hydrogen-bonded organic framework (HOF) that can adsorb NH uniquely in an S-shape (type IV) fashion.
