研究目的
To examine the photocatalytic effects of ZnO nanoparticles multilayer films on the degradation of organic dyes under ultraviolet light.
研究成果
Zinc oxide nanoparticles and their multilayer films were successfully synthesized and showed effective photocatalytic degradation of organic dyes under ultraviolet light, with methylene blue being the most effectively degraded.
研究不足
The study focuses on the photocatalytic degradation of specific organic dyes under controlled conditions, which may not represent all possible environmental contaminants.
