WebFeb 24, 2015 · We thus turned our attention to derivatives of UiO-66 in order to probe the importance of functional groups on the hydrolysis rate. Three UiO-66 derivatives were explored; UiO-66-NO 2 and UiO-66-(OH) 2 showed little to no change in hydrolysis rate. However, UiO-66-NH 2 showed a 20 fold increase in hydrolysis rate over the parent UiO-66 …
