Abstract

Abstract: A facile, versatile, genuine green route that uses starch‐derived carbonaceous spheres as the templates and carbon source for tailor‐made ZnO spherical structures is described. A simple adjustment of the thermal treatment permits the generation of either ZnO/C solid microporous spheres or ZnO hollow spheres, the later with controlled diameter and shell morphology. The spherical structures demonstrate good photocatalytic activity for the visible light degradation of methylene blue. Furthermore, ZnO/C has promising electrochemical capacitor applications and good electrochemical and mechanical stability.
