Cardanol, a well known hazardous byproduct of the cashew industry, has been used as starting material for the synthesis of useful differently substituted “cardanol-based” porphyrins and their zinc(II), copper(II), cobalt(II) and Fe(III) complexes. Novel composites prepared by impregnation of polycrystalline TiO2 powder with an opportune amount of “cardanol-based” porphyrins, which act as sensitizers for the improvement of the photo-catalytic activity of the bare TiO2, have been used in the photodegradation in water of 4-nitrophenol (4-NP), which is a toxic and bio-refractory pollutant, dangerous for ecosystems and human health.
卡达诺醇是腰果工业中著名的有害副产品,已经被用作合成各种不同取代的“卡达诺基”卟啉及其锌(II)、铜(II)、钴(II)和铁(III)复合物的原料。通过将多晶TiO2粉末浸渍适量的“卡达诺基”卟啉制备的新型复合材料,作为光敏剂用于提高裸TiO2的光催化活性,这些复合材料已用于水中降解4-硝基苯酚(4-NP),这种物质是一种对生态系统和人类健康有害的有毒和难降解的污染物。
