Preparation of a novel composite electrode based on N-doped TiO2-coated NaY zeolite membrane and its photoelectrocatalytic performance

For the first time the preparation of the N-doped TiO2-coated NaY zeolite membrane (N-doped TiO2/NaY zeolite membrane) as an electrode material for photoelectrocatalysis has been achieved and reported. The XRD, SEM, UV–vis and XPS techniques were used to characterize the structure of the N-doped TiO2/NaY zeolite membrane. The results verified that the surface of the N-doped TiO2/NaY zeolite membrane was coated by TiO2 nanoparticles of ca. 20 nm size and exhibited a distinct red-shift in the UV–vis spectra compared to N-doped TiO2. The photoelectrocatalysis performance of the N-doped TiO2/NaY zeolite membrane electrode was evaluated by phenol degradation. The results revealed it is a promising novel electrode material for application of photoelectrocatalysis in the removal of organic contaminants in waste water.
