Abstract

Using infrared spectroscopy combined with ab initio methods we study reactions of H2O and CO inside the confined spaces of Zn-MOF-74 channels. Our results show that, once the water dissociation reaction H2O → OH + H takes place at the metal centers, the addition of 40 Torr of CO at 200 °C starts the production of formic acid via OH + H + CO → HCO2H. Our detailed analysis shows that the overall reaction H2O + CO → HCO2H takes place in the confinement of MOF-74 without an external catalyst, unlike the same reaction on flat surfaces. This discovery has several important consequences: it opens the door to a new set of catalytic reactions inside the channels of the MOF-74 system, it suggests that a recovery of the MOF's adsorption capacity is possible after it has been exposed to water (which in turn stabilizes its crystal structure), and it produces the important industrial feedstock formic acid.
