ZnO with various morphologies has been obtained by microwave hydrothermal method with the assistance of ethylene glycol (EG). By adjusting the concentration of EG in the system, the morphology of sample can be tuned from irregular disks to twin crystal rods, to shuttle shape, and finally to sphere shape. It is founded that the concentration of EG plays an important role in adjusting system pressure, which significantly influence the reaction speed and final shape of products. The photocatalytic activity of as-prepared ZnO with different morphologies in aqueous solution was investigated by bleaching dye rhodamine B under Xe lamp. The sphere shape sample possesses the most efficient photocatalytic properties, which can completely photodegradate rhodamine B in 50 min.
