摘要

Metal oxide nanomaterials as visible light photocatalysts are of special interest for the research community. We report synthesis and properties of nanocomposites of zinc oxide with cobalt oxide by cryomilling followed by pulsed laser fragmentation technique for the first time. Structure, morphology, composition, optical properties and visible light photocatalysis of these nanocomposites are investigated. Morphological analysis showed that pulsed laser fragmentation in water resulted with nanoflakes. The optical absorption in visible range was enhanced by addition of cobalt oxide. Chemical states and mapping studies of the sample surfaces showed their uniformity of elemental composition. They were used for photocatalytic studies under visible light from a solar simulator (200 W) using methylene blue dye as the contaminant. These nanocomposites showed good stability and cyclic photocatalytic activity under visible light irradiation. The results show enhanced and cyclic visible light photocatalytic activities of metal oxide nanocomposites designed by pulsed laser fragmentation.
