Abstract

The metal phthalocyanines (MPCs)-adsorbed Nafion (Nf) membranes (Nf/MPCs) are prepared and used for the photocatalytic reduction of nitrite ion. The selective formation of NH4OH is observed when the Nf/MPC membrane is dipped in nitrite ion solution and photolysed in the presence of sacrificial electron donor such as triethanolamine (TEA). The Nf/MPC membranes behave as p-type semiconductors. The photosensitized reaction mechanism of the photocatalytic reduction of NO2 - to NH4 + formation is explained by the reaction of the e- c b with nitrite ion and the hole (h+ v b) with TEA.
