In catalysts for CO hydrogenation, the interface between metal nanoparticles (NPs) and the support material is of high importance for the activity and reaction selectivity. In Pt NP-containing UiO Zr-metal-organic frameworks (MOFs), key intermediates in methanol formation are adsorbed at open Zr-sites at the Pt-MOF interface. In this study, we investigate the dynamic role of the Zr-node and the influence of HO on the CO hydrogenation reaction at 170 °C, through steady state and transient isotope exchange experiments, HO cofeed measurements, and density functional theory (DFT) calculations.
