Abstract

We developed a method for using atomic layer deposition (ALD)-formed layers of Al2O3 as a sacrificial template to generate MIL-53(Al). The MOF shell in the CeO2/Pd@MIL-53(Al) configuration not only stabilized the Pd nanoparticles, but also regulated the selectivity of the hydrogenation of unsaturated aldehydes. This work represents the first demonstration of ALD-formed layers of metal oxides serving as sacrificial templates in the design of MOF-shell-based sandwich-type structures.
