研究目的
To synthesize and optimize visible-light responsive Ce-doped titanate nanotubes for enhanced degradation of polluting dyes in aqueous environments.
研究成果
Ce-doped titanate nanotubes exhibited superior photocatalytic activity under visible light, making them highly effective for decomposing color dyes in wastewater. The crystallinity and absorption range improvements due to Ce-doping highlight their potential for environmental applications.
研究不足
The study does not address the long-term stability and reusability of the Ce-doped titanate nanotubes in practical wastewater treatment applications.
1：Experimental Design and Method Selection:
