Catalytic hydrodeoxygenation (HDO) of bio-oil is an effective and challenging route to the efficient utilization biomass with rich oxygen-containing groups. Herein, highly dispersed Pd nanoparticles (NPs) anchored on a N-doped hollow carbon sphere (NHCS) were constructed effectively catalyze chemoselective HDO bio-oil-derived vanillin. The optimized Pd/NHCS-900 catalyst presented high 99% conversion 98% selectivity 2-methoxy-4-methylphenol (MMP) within 45 min under very mild conditions 50 °C 1 atm H2. incorporated N species in NHCS support its hierarchical porous structure facilitate dispersion stabilization NPs, resulting formation NPs excellent stability. Moreover, presence strong electronic metal–support interaction between produced surface electron-rich active which could enhance adsorption activation reactants, thereby exhibiting intrinsic catalytic activity large turnover frequency (TOF) 1700.3 h–1. Kinetic study density functional theory (DFT) calculations demonstrated reaction pathway corresponding mechanism. These findings pave way for development stable metal catalysts sustainable conversion.

With the continuous depletion of fossil resources and deterioration global climate, it is particularly urgent to find green sustainable renewable replace non-renewable resources. Renewable biomass, which converts stores light energy into chemical through photosynthesis by plants, has received widespread attention due its simultaneous resource properties. Therefore, this article focuses on lignocellulose, an important component in fields conversion high-value-added preparation. A detailed review was conducted application catalysts biomass bio-char, bio-oil, bio-gas, high-value added chemicals their derivatives, represented 5-hydroxymethylfurfural (5-HMF) levulinic acid (LA). At same time, difficulties challenges encountered were analyzed, new ideas proposed for future development directions, so as provide pathways efficient chemicals.
