In current work, surfactant free synthesis of Sr2CeO4 nanostructures by co-precipitation process were reported. This method require lower firing temperature (700 °C) compare to the previous reports (above 1000 °C). This study shows that by controlling the reaction conditions such as kind of precipitating agent, surfactant and calcination temperature, the Sr2CeO4 nanostructures with various morphologies were prepared. Up to now, luminescence properties of Sr2CeO4 structures received great attention, while we focused on the photocatalytic activity of Sr2CeO4 nanostructures. Results show that the Sr2CeO4 nanostructures have exhibited excellent photodegradation performance of Acid red 88 azo dye as water pollutants under UV light irradiation.
