Solid vs. hollow oxide spheres obtained by hydrothermal carbonization of various types of carbohydrates†
Abstract
Saccharide derived, self-templated carbonaceous spheres with embedded Zn (and Co) were obtained by a versatile one-pot hydrothermal synthesis and proved to be multipurpose precursors for full solid or hollow oxide spheres. Saccharide/Zn2+ ratios and saccharide type affect the morphology (size, shell thickness, surface roughness) of the oxide spheres.
