Caption: This is a cross-section of the iron-based MOF bound to six ethylene molecules, as determined by neutron diffraction. The MOF consists of a carbon (gray) and oxygen (red-orange) framework with iron atoms (yellow-orange) at strategic sites to bind the ethylene carbon atoms. The attraction between the iron and unsaturated hydrocarbons like ethylene (olefins) allows the MOF to adsorb these hydrocarbons, separating them from saturated hydrocarbons (paraffins) even at high temperatures.
