China A R T I C L E I N F O A B S T R A C T Article history: The photocatalytic performance of Mg-doped ZnO (MZO) nanoparticles, synthesized through the Received 29 November 2015 Received in revised form 14 April 2016 polyacrylamide polymer method, was investigated by the photodegradation of the methylene blue (MB) Accepted 7 May 2016 solution. The nanoparticles were characterized by X-ray diffractometry, X-ray photoelectron Available online 13 May 2016 spectroscopy, and UV–vis absorption spectrum. The results demonstrate that the catalysts present different photodegradation performances with varying calcination temperatures of the as-synthesized Keywords: Mg-doped ZnO precursor. It is found that the highest photodegradation of the MB solution was achieved Polyacrylamide polymer method by the catalyst with a 47 nm particle size, which had the lowest oxygen vacancies.
