Boosting the photocatalytic activity of Ti-MOF via emerging with metal phthalocyanine to degrade hazard textile pigments
Source abstract
Abstract
Metal-organic frameworks (MOFs) have shown a great potential for producing efficient and eco-friendly photocatalysts. Furthermore, phthalocyanines (PCs) are promising materials in photocatalytic reactions because of their unique adsorption and photosensitizing properties. Here, three phthalocyanines (Pcs) derivatives with Al 3+ and Co 2+ ions as the central metal were prepared to attach them to the MOFs matrix. The photocatalytic decay performance of methylene blue (MB) and methyl orange (MO) and their mixtures were investigated under visible light illumination. The photocatalyst NH 2-MIL-125, Al-PcCl@NH 2-MIL-125, CoPc@NH 2-MIL-125, and CoPcPA@NH 2-MIL-125 show 0.01, 0.012, 0.035, and 0.046 min −1 MB degradation rate, respectively, while, the degradation rates of MO were 0.021, 0.027, 0.052 and 0.082, respectively. Amazingly, the degradation rates of MB in presence of MO showed boosted photocatalytic decomposition with the degradation rate of 0.066, 0.069, 0.085, and 0.120 min −1 , respectively. This study illustrates a high performance for utilizing porous MOF-based materials not only as supports but as electron acceptors that enhance both photostability and photocatalytic activity.
