Mar 03, 2015 · Mg-MOF-74 has attracted intense attention due to its high CO 2 uptake ability. In this work, a new strategy by using magnesium oxide as seeds was developed to synthesize a dense, defect-free Mg-MOF-74 membrane with hydrogen-selectivity.

Increasing demands in the field of sensing, especially for gas detection applications, require new approaches to chemical sensors. Metal–organic frameworks (MOFs) can play a decisive role owing to their outstanding performances regarding gas selectivity and sensitivity.
