can-1326	Zhang, Yuanyuan; Huang, Chi; Sun, Li; Wang, Xueying	Synthesis of ZnO nanometer powders doped with Ce4+ ions and the photocatalytic degradation of dying wastewater	2021	8	.pdf	application/pdf	4280	219	53	Under alkaline con- ditions, OH- can trap holes, and the generated ▪OH harms photocatalytic degradation. Excessive acidity and alkalinity may cause changes in the structure of nano ZnO, which is not conducive to photocatalytic degradation.	cache/can-1326.pdf	txt/can-1326.txt
