研究目的
Investigating the photocatalytic activity of Ag/TiO2 nanotubes in thiocyanation reactions of N-bearing aromatic and heteroaromatic compounds under visible light irradiation.
研究成果
Ag/TiO2 nanotubes exhibit high photocatalytic activity under visible light for the thiocyanation of N-bearing aromatic and heteroaromatic compounds. The method is efficient, environmentally friendly, and offers good to excellent yields of the desired products. The photocatalyst can be recycled and reused without significant loss of activity.
研究不足
The reaction efficiency is dependent on the wavelength of the light source, with lower wavelengths yielding better results. The presence of electron-donating groups on the substrates generally leads to higher yields.
