Synthesis of Pd/ZnO nanocomposites with high photocatalytic performance by a solvothermal method

► Pd/ZnO nanocomposites can be obtained through a facile one-pot solvothermal method. ► No extra surfactant or template was added in the reaction process. ► Pd/ZnO shows good photocatalytic activity and high stability. ► Pd/ZnO shows strong PL in UV region and weak emission in visible region.
