摘　　要：Semiconductor heterojunction engineering and three-dimensional(3D)architecture con-struction have been considered highly desirable strategies to enhance photocatalytic perfor-mance.Herein,a BiOI/ZnO composite photocatalyst with a 3D flower-like architecture was successfully prepared,whichwas stably immobilized on three-dimensional porous lignocel-lulosic biomass Juncus effusus(JE)fiber.The outstanding photocatalytic performance of the BiOI/ZnO-JE fiber was confirmed by the degradation of tetracycline hydrochloride(TC,90%),ciprofloxacin(CIP,79%),and norfloxacin(NOR,81%).The enhanced photocatalytic activities were mainly attributed to the synergistic absorption performance of the lignocellulosic JE and the effective transfer and separation of charges.Moreover,the hydroxyl(·OH)and super-oxide radicals(·O_(2)^(−))are themain reactive species in the photocatalytic process according to the analysis.This work may provide a novel perspective for constructing high-performance lignocellulosic-based photocatalytic materials.
