Adsorption and transformation of PAHs from water by a laccase-loading spider-type reactor

► Laccase-loading spider-type reactor (LSTR) is got by emulsion electrospinning. ► LSTR consists of beads-in-string fibers with more laccase and higher activity. ► LSTR can achieve the rapid and efficient removal of PAHs from water. ► Aquatic environmental factors have little influence on the PAH removal by LSTR. ► A synergetic mechanism includes adsorption, directional migration and degradation.
