Highly Dispersed Pd on Zeolite/Carbon Nanocomposites for Selective Hydrodeoxygenation of Biomass-Derived Molecules under Mild Conditions

Herein, a defective zeolite–carbon (CFR@HZSM-5) nanocomposite-supported nano-scale Pd catalyst (Pd/CFR@HZSM-5) was facilely synthesized for selective “H2-free” hydrodeoxygenation (HDO) of vanillin (VL) under mild conditions. The optimal Pd/CFR@HZSM-5(2:1) catalysts show excellent activity (the 99% yield to 2-methoxy-4-methylphenol) and high turnover frequency in polymethylhydrosiloxane at 60 °C. According to spectral analysis, there is an...
