Chiral Metal-Oxide Nanofilms by Cellulose Template Using Atomic Layer Deposition Process
In
this article, we describe an advance approach for the fabrication
of chiral metal-oxide nanofilms. Our approach is based on the atomic
layer deposition of titania and alumina nanofilms onto cellulose microfibers,
used as chiral templates, leading to the formation of chiral nanofilms
with a spatial fibrous structure. The chiral nanofilms were extensively
characterized by X-ray photoelectron spectroscopy and high-resolution
electron microscopy. The chiral property of the produced titania nanofilms
was studied by enantioselective adsorption experiments using circular-dichroism
spectroscopy and chiral high-performance liquid chromatography. We
demonstrate the application of the titania chiral nanofilms for enantioselective
crystallization. Overall, the basic principle for the preparation
of chiral nanofilms by atomic layer deposition is demonstrated, as
well as their uses for several enantioselective applications
