XÚC TÁC QUANG TRÊN CƠ SỞ C-ZnO CỐ ĐỊNH TRÊN XENLULOZƠ, ỨNG DỤNG PHÂN HỦY METHYLENE XANH TRONG NƯỚC

Tóm tắt

In this study, C-doped ZnO nanomaterials immobilized on cellulose (CZX) were synthesized through two
steps. First, nanometer-sized C-ZnO was produced using a one-step hydrothermal process. Next, a simple
papermaking procedure using alkyl ketene dimer (AKD) linked C-ZnO to cellulose in levels ranging from
10% to 60%. The crystal structure, bond vibration, and optical absorption properties of the materials were
examined. Additionally, we examined photocatalytic activity and reusability using methylene blue (MB)
degradation under visible light. The results showed that the CZX20 material, which was made of 20% C
ZnO and cellulose, was the most effective to degrade MB, reaching yield of 98% after 210 minutes of light.
The MB degradation efficiency of CZX20 reached over 94.4% after 4 reuses. These results suggest that the
new material C-ZnO/cellulose had the potential to be employed in water treatment under visible light with
the advantages of low cost, environmental friendliness, ease of use, ease of recovery and ease of recycling
