ABSTRACT Biomass‐based porous organic polymers (Bio‐POPs) as a class of highly promising novel materials had garnered significant attention in the field of natural organic materials research due to their unique properties and renewable nature. Bio‐POPs were synthesized from abundant, renewable biomass resources through specific preparation methods, which could effectively serve as alternatives to porous organic polymers (POPs) synthesized from fossil resources. They exhibited highly developed porous structures and outstanding functional characteristics, offering significant advantages in sustainable resource utilization. Currently, Bio‐POPs demonstrated broad application prospects and scientific value in crucial fields. Through the continuous optimization of synthesis processes, it was anticipated that advanced Bio‐POPs with superior performance and lower production costs could be developed, thereby further expanding their application scopes. This review focused on Bio‐POPs, exemplified by lignin, cellulose, and chitosan. Their preparation methods and structural properties, especially in terms of porosity, were reviewed and compared, with a focus on describing their respective application potentials and bottlenecks in adsorption, heterogeneous catalysis, energy storage, and biomedicine. We thoroughly analyzed the synthesis method, porosity, and application for each type of Bio‐POPs, while also outlining future development prospects of Bio‐POPs, which would offer valuable reference and insights for research and application within this field.
