DarkLight Catalyst

The DarkLight™ Catalyst is an advanced, biosynthesised titanium dioxide (TiO₂) photocatalyst that functions efficiently without the need for visible or ultraviolet light. Developed through a green synthesis process using natural extracts from Hibiscus sabdariffa, the material features an oxygen-deficient “black” TiO₂ structure capable of photocatalytic activity under near-infrared and even dark conditions. This breakthrough enables pollutant degradation and environmental purification in enclosed or low-light environments, eliminating the dependence on artificial light sources. By fine-tuning the material’s electronic bandgap, the process enhances its performance across the visible and infrared spectra, significantly expanding the operational range of photocatalysis. The DarkLight™ Catalyst represents a sustainable and energy-independent innovation for next-generation water treatment, air purification, and self-cleaning applications, combining green chemistry, high efficiency, and environmental adaptability.
