Tuning the mesopore size of lignin-based porous carbon via salt templating for kraft lignin decomposition

A novel and practical CaCl2 salt templating method is used to tune the pore size of carbon materials from calcium lignosulfonate. In-situ crystalized CaCl2 particles serve as templates for mesopores and as carbonization substrates. Hierarchical carbons are constructed using coupled SiO2 spheres and CaCl2 templates. The SiO2 spheres improve the pore size assigned to CaCl2 particles and high CaCl2:lignin mass ratios benefit large CaCl2 crystals to improve the size of mesopores. The porous carbons are used as supports of molybdenum carbide (MoC) with C-C and C-O cleavage activity for Kraft lignin decomposition into aromatic monomers. The results show that MoC over porous carbon supports achieves the highest aromatic yield of 0.716?g/g Kraft lignin and exhibits high stability of aromatic yields. Suitable pore size for lignin macromolecule diffusion significantly enhances the catalytic performance of molybdenum carbide.
