Zinc oxide (ZnO) nanorods were grown on a paper support prepared from soft wood pulp. The photocatalytic activity of a sheet of paper with ZnO nanorods embedded in its porous matrix has been studied. ZnO nanorods were firmly attached to cellulose fibers and the photocatalytic paper samples were reused several times with nominal decrease in efficiency. Photodegradation of up to 93% was observed for methylene blue in the presence of paper filled with ZnO nanorods upon irradiation with visible light at 963 Wm for 120 min. Under similar conditions, photodegradation of approximately 35% was observed for methyl orange. Antibacterial tests revealed that the photocatalytic paper inhibits the growth of under room lighting conditions.
氧化锌(ZnO)纳米棒生长在由软木浆制备的纸质载体上。对多孔基质中嵌入ZnO纳米棒的纸张的光催化活性进行了研究。ZnO纳米棒牢固地附着在纤维素纤维上,光催化纸样品可重复使用多次,效率仅有名义上的降低。在用963 Wm的可见光照射120分钟后,在填充有ZnO纳米棒的纸张存在下,亚甲基蓝的光降解率高达93%。在类似条件下,甲基橙的光降解率约为35%。抗菌测试表明,光催化纸在室内光照条件下可抑制细菌生长。
