The invention relates to the technical field of photocatalytic degradation materials, and discloses a ZnO-WO 3 heterojunction photocatalytic composite degradation material, comprising the following formula raw materials and components: porous nano-WO 3 , nano-cellulose, Zn(NO 3 ) ) 2. Ethanolamine. The ZnO-WO 3 heterojunction photocatalytic composite degradation material, the porous nano-WO 3 has abundant pore structure and huge specific surface area, which increases the contact area with light radiation and enhances the composite material's ability to light energy. Responsiveness and utilization, porous nano-WO 3 adsorbed nanocellulose, hydroxyl groups in nanocellulose complexed and adsorbed Zn 2+ and nucleated heterogeneously, nanocellulose was a carbon source, and C-doped cellulose was prepared ZnO, C doping replaces part of the lattice of O, reduces the energy band width of ZnO, and promotes the migration of photogenerated electrons of ZnO. The separation of holes enhances the photocatalytic degradation performance of the composites. |
