Title
Highly active NiO–CaO photocatalyst for degrading organic contaminants under visible-light irradiation
Abstract

A series of NiO–CaO photocatalysts have been successfully prepared by a precipitation–calcination method. The specimen was characterized by powder X-ray diffraction and UV–vis diffuse reflectance spectra. The UV–vis diffuse reflectance spectra revealed that the NiO–CaO samples exhibited absorptions in a wide visible-light range of 400–600 and 700–800 nm. These results showed that the NiO–CaO samples might possess excellent photocatalytic performances in the wide visible-light region. By using photocatalytic degrading methyl blue as the model reaction, the NiO–CaO samples showed higher photocatalytic activity than those of NiO, CaO, and commercial TiO2 under visible-light illumination.
