Effects of the novel catalyst Ni-S₂O₈ ^2--K₂O/TiO₂ on efficient lignin depolymerization.

ABSTRACT: To improve the utilization of lignin, much effort has been devoted to lignin depolymerization with the aim to decrease waste and enhance profitability. Here, a dual property (acid and base) catalyst, namely S₂O₈ ^2--K₂O/TiO₂, was carefully researched. Upon loading S₂O₈ ^2- and K₂O onto TiO₂, acid and base sites emerged, and S₂O₈ ^2- and K₂O mutually enhanced the acid and base strengths of the catalyst enormously; this indeed facilitated lignin depolymerization. Under appropriate conditions, the yields of liquid product, petroleum ether soluble (PE-soluble) product and total monomer products were 83.76%, 50.4% and 28.96%, respectively. The co
