Novel Catalytic Systems to Convert Chitin and Lignin into Valuable Chemicals

Abstract

This review briefs the emerging strategies for the designing of catalysts and catalytic systems to upgrade waste biomass into value-added chemicals, with an emphasis on the efforts and advances in our group. The review covers the valorization of chitin and lignin materials, which are most abundant N-containing and the most abundant aromatic polymers, respectively. In the chitin part, we show case existing examples on chitin monomer and chitin transformation into renewable, N-containing chemicals. Oxidation, hydrolysis, dehydration reactions will be introduced. In lignin part we mainly introduce novel catalyst for lignin hydrogenolysis, in particular Ni based monometallic and bimetallic catalysts. The structure–activity correlations will be discussed in detail. We finally describe some of the undergoing works in the group and highlight a few potential directions worth investigation in the future.
