Abstract:

Nuclear magnetic resonance (NMR) is an important characterization method for the depolymerization of lignocellulosic biomass and its structure evolution analysis. The accurate NMR analysis facilitates the selective transformation of different biomass components. In this review, the principles of NMR are presented. Four types of NMR experimental methods, including 1H NMR, 13C NMR, 31P NMR and 2D HSQC, and their applications in the structure elucidation, qualitative and quantitative analysis of products, reaction path and catalytic depolymerization mechanism of lignocellulose are mainly introduced. Finally, the main problems and perspectives of NMR method in valorization of lignocellulosic biomass are discussed.

Key words: lignocellulose, 1H NMR, 13C NMR, 31P NMR, 2D HSQC
