Abstract

A series of lanthanide–naphthalenedicarboxylates–modified TiO2 (Ln(NDC)-TiO2) photocatalysts were prepared via simple hydrothermal method using Tm, Er, Nd, Ho, Eu, Tb, Yb, or La as metal and 2,6-naphthenedicarboxylic acid as ligand. The photocatalysts were characterized by diffuse reflectance spectroscopy (DRS), photoluminescence spectroscopy (PL), and scanning electron microscopy (SEM). The photocatalytic properties were investigated by employing the photodegradation of phenol in the aqueous phase as a model pollutant. To provide insight into the reactive individuals participating in the degradation mechanism, a test with scavengers was also performed.
