Metal-organic framework (MOF)-basedd erivatives have been found to be promisingh eterogeneousc atalysts for organic transformations. Herein, hollow-structureC u-MOFs derived by reduction of Cu 3 (BTC) 2 (BTC = 1,3,5-benzenetricarboxylate;d enoted as RCB) were prepared by using hydrazine hydrate as ar educing agent under variousc onditions. The influence of hydrazine hydrate induced the structure of Cu 3 (BTC) 2 and led to dynamic variation in the interior and exterior as well as oxidation states of the Cu ion. The synthesized materials were characterized by SEM, TEM, N 2 sorptioni sotherms, XRD, and XPS. The product of the catalytic reaction was observed by GC-MS. In addition, the prepared RCBs were found to have excellent catalytic activity and selectivity for benzyl alcohol oxidation when assisted by 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO).
