One‐pot synthesis of ultra‐small pt dispersed on hierarchical zeolite nanosheet surfaces for mild hydrodeoxygenation of 4‐propylphenol

Abstract

The rational design of ultra‐small metal clusters dispersed on a solid is of crucial importance in modern nanotechnology and catalysis. In this contribution, the concept of catalyst fabrication with a very ultra‐small size of platinum nanoparticles supported on a hierarchical zeolite surface via a one‐pot hydrothermal system was demonstrated. Combining the zeolite gel with eth-ylenediaminetetraacetic acid (EDTA) as a ligand precursor during the crystallization process, it al-lows significant improvement of the metal dispersion on a zeolite support. To illustrate the benefi-cial effect of ultra‐small metal nanoparticles on a hierarchical zeolite surface as a bifunctional cata-lyst, a very high catalytic performance of almost 100% of cycloalkane product yield can be achieved in the consecutive mild hydrodeoxygenation of 4‐propylphenol, which is a lignin‐derived model molecule. This instance opens up perspectives to improve the efficiency of a catalyst for the sustainable conversion of biomass‐derived compounds to fuels.
