How Does Light Source Wavelength Affect Catalytic Activity?
The wavelength of the light source is a critical factor in determining the efficiency of a photocatalytic process. Different catalysts are activated by different wavelengths of light. For instance, titanium dioxide (TiO₂) is commonly activated by UV light, while other materials like graphitic carbon nitride (g-C₃N₄) can be activated by visible light. The choice of wavelength can influence the rate of reaction, selectivity, and overall energy efficiency.
