文摘
- •
Creation of void in CdS/SiO2 nanorod core–shell structure by Ar ion laser etching.
- •
Core size was reduced from 6 to 2.4 nm as a function of wavelength of light used.
- •
Metal loading improved the photodegradation efficiency to ∼91% under visible light.
- •
Metals follow the order – Pt > Au > Rh > Pd > Ag ∼ Cu due to their different nature.
- •
Plausible degradation pathway was proposed for mineralization of methyl orange.
