MOFs as acetylene adsorbents: The adsorption of acetylene on the isostructural metal–organic frameworks CPO-27-M (where M=Fe, Co and Ni) is studied by FTIR, UV/Vis spectroscopy, and calorimetric isotherm measurements. The results show that M–O pairs act as the adsorption sites in these materials and that the Ni analogue is the strongest acetylene adsorbent of the series.
