Scheme 1. The formation process of carbon frameworks derived from biomass wood and the bond cleavage of lignin in wood. (a and b) Schematic illustration of the fabrication and the structures of ATP, WTP and BTP. (c) Cleavage location of lignin bonds in ATP, WTP and BTP. (d) GC-MS analysis of the solution after the hydrothermal reaction of ATP, WTP and BTP (pie chart illustrates the content of the pyrolysis product).
