Lignocellulosic biomass, which is the most abundant and bio-renewable resource on the earth, having a great potential for sustainable production of chemicals and fuels. Herein, non-noble metal-based catalyst comprising amorphous ZnO and crystalline Co nanoparticles embedded on nitrogen-doped carbon nanotubes (ZnO/Co@N-CNTs) can completely remove the C=O group in vanillin to form creosol with a 100% yield under mild reaction conditions. Also, kraft lignin and bio-oil derived from concentrated strong acid hydrolysis lignin were converted over ZnO/Co@N-CNTs, high degrees of deoxygenation of 74.2% and 34.4%, respectively. The mild HD/HDO conditions, use of water as the solvent, and use of a non-noble and magnetically separable metal catalyst can allow us to develop a cost-effective, easy to scale up, and environmental-benign biofuel and biochemical production processes. |
