Abstract

Abstract Bicontinuous porous materials, which possess 3D interconnected network and pore channels facilitating the mass diffusion to the interior of materials, have demonstrated their promising potentials in a large variety of research fields. However, facile construction of such complex and delicate structures is still challenging. Here, an amine‐mediated polymerization‐induced fusion assembly strategy is reported for synthesizing polyphenol‐based bicontinuous porous spheres with various pore structures. Specifically, the fusion of pore‐generating template observed by TEM promotes the development of bicontinuous porous networks that are confirmed by 3D reconstruction. Furthermore, the resultant bicontinuous porous carbon particles after pyrolysis, with a diameter of ≈600 nm, a high accessible surface area of 359 m2 g−1, and a large pore size of 40–150 nm manifest enhanced performance toward the catalytic degradation of sulfamethazine in water decontamination. The present study expands the toolbox of interfacial tension‐solvent‐dependent porous spheres while providing new insight into their structure‐property relationships.
