In this review, we highlight the key aspects of thermochemical upgrading, including the thermal deconstruction of biomass feedstock, selective production of high-value chemicals, and the preparation and application of carbon-based materials. Particularly, the application of sustainable and economical pretreatments is vital for promoting efficiency in the follow-up thermochemical transformation. The introduction of catalytic materials greatly contributes to the selective production of a series of building blocks and high-value chemicals. Furthermore, it is clear that the future application of porous biochar strongly depends on the modification methods. Last but not least, the challenges and future research directions for the large-scale utilization of biomass are proposed, where effective coupling of thermal deconstruction with further upgrading into a wide range of derivatives should be given significant emphasis.
