Abstract	결정핵-매개 소프트-용액 방법을 이용하여 판상형 ZnO 나노입자를 합성하였다. 합성된 판상형 ZnO 나노입자는 많은 결함이 존재하는 (0001)면이 발달하여 상업적인 ZnO 나노입자 보다 광촉매 특성이 우수하였다. 또한, 판상형 ZnO 나노입자의 세포독성이 실리카 코팅을 통해 감소함을 확인하였다. 마지막으로 판상형 ZnO를 합성하는데 필요한 성장용액의 다양한 시 약 조건들을 변화시키면서 상업적인 적용이 가능한 수백 그램 스케일로 대량합성 하는데 처음으로 성공하였다. ZnO nanoplates were prepared by seed-mediated soft-solution process. Photocatalytic property of ZnO nanoplates was superior to that of conventional ZnO nanoparticles owing to the enhanced (0001) plane with large defect sites. In addition, we found that silica coating method could provide to reduce cytotoxicity of ZnO nanoplates. Finally, we have successfully synthesized for the first time large-scale synthesis of plate-type ZnO as few hundreds gram scale for industrial applications through controlling various reagents of growth solution.
