Mesoporous carbon nitride supported MgO for enhanced CO capture.

The growing concern about the environmental consequences of anthropogenic CO emissions significantly stimulated the research of low-cost, efficient, and recyclable solid adsorbents for CO capture. In this work, a series of MgO-supported mesoporous carbon nitride adsorbents with different MgO contents (xMgO/MCN) was prepared using a facile process. The obtained materials were tested for CO capture from 10 vol% CO mixture gas with N using a fixed bed adsorber at atmospheric pressure.
