Often electrochemical means of analysis employ hierarchically structured materials (HSM) as an electroactive additive. The superiority of such materials over regular-structured ones is manifested in increased functionality resulting from increased surface area, multi-modal porosity, and anisotropy of properties. One of them is zinc oxide - an affordable and safe substrate to build up hierarchical structures with the use of a wide range of methods: sol-gel, hydrothermal, template-based, etc. In our work, we investigated the possibility of forming a hierarchical structure of zinc oxide using a soft, accessible molecular template–a sugar-based surfactant. As a result, we developed conditions for obtaining zinc oxide spheres with a narrow size distribution using a commercially available, cheap and eco-friendly alkyl glycoside. Obtained spheres comprised flat flakes, which are a flat aggregate of oxide nanoparticles, thus exhibiting structural regularity on three scale levels. Wurzite nanocrystal aggregation was assumed to proceed through orthogonal 100 and 002 facets, while the most abundant one (101) was stabilized with the sugar moiety of the soap molecule. Surfactant stabilization of the facet also well explains the minimal contact of the planar flakes, comprising the microspheres.
