Abstract

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.

摘要

腰果酚是腰果工业的一种众所周知的有害副产品，已被用作合成有用的不同取代基“腰果酚基”卟啉及其锌(II)、铜(II)、钴(II)和 Fe(III)配合物的起始原料。通过将适量的“腰果酚基”卟啉浸渍到多晶 TiO₂ 粉末中制备的新型复合材料，作为提高裸 TiO₂光催化活性的敏化剂，已用于水中 4-硝基苯酚（4-NP）的光降解，4-NP 是一种有毒且生物难降解的污染物，对生态系统和人类健康构成危险。
