摘要
Highly dispersed Pd anchored on PTA modified ZrO 2 was synthesized. Excellent catalytic performance for HDO of lignin-derivatives under mild condition has been realized with the Pd-PTA/ZrO 2 catalyst. • Highly dispersed Pd anchored on PTA-modified ZrO 2 was constructed. • Pd-PTA/ZrO 2 displayed super catalytic activity for the HDO of lignin-derivatives. • The introducing of PTA not only can stabilize Pd species, but also act as acid sites. Production of biofuels and value-added chemicals from renewable biomass is a strategy with great promise to replace petrochemicals. Herein, we developed an efficient method to fabricate highly dispersed Pd anchoring on phosphotungstic acid (PTA)-modified ZrO 2 . The optimized metal–acid bifunctional catalyst, Pd-PTA/ZrO 2 , displayed excellent catalytic performance for the hydrodeoxygenation of lignin-derivatives under mild conditions. High conversion of vanillin and high selectivity of 2-methoxy-4-methylphenol can be achieved at 80 °C for 90 min under 1 atm H 2 , which overcame most of the reported catalysts. The outstanding catalytic activity can be attributed to the large surface area, moderate acid strength, the synergetic effect of the active metal and ZrO 2 support. This study provides a feasible route to prepare highly dispersed catalysts with superior catalytic performance for bio-fuel upgrading.
