Zinc oxide formation in seed-assisted and controlled double-jet precipitation (CDJP) was explored. Results show that the formation of ZnO involves the initial surface precipitation of β-Zn(OH)2 intermediates on seed surfaces, followed by fast surface phase transformation to ZnO. During this process, the seeds play the role of crystallization catalysts to promote ZnO formation in a short time at room temperature via changing the precipitation pathway. Meanwhile, CDJP ensures the effects of the seeds by controlling the solution supersaturation.
