Abstract: A simple and economical citrate-mediated hydrothermal route has been developed to fabricate three-dimensional hierarchical ZnO microarchitectures with high surface-to-volume ratio and large population of unconventional (0001) surface planes. This complex architecture with flowerlike morphology is assembled by many interleaving nanosheets which have ultrathin thickness of about 5 nm. According to the experimental results, a growth mechanism which involves the assembly of the nanosheets from nanoparticles into flowerlike morphology is proposed. I...
