A general, eco-friendly synthesis procedure of self-assembled ZnO-based materials with multifunctional properties

A bioinspired one-pot approach for the synthesis of ZnO-carbohydrate hierarchical architectures was developed. The synergy between a saccharide (mono-, di- or polysaccharide) that contains d-glucose units and triethanolamine is the key parameter of the synthetic methodology. The morphology of the ZnO composites is dictated by the saccharide used, and rod, spindle, solid and hollow spherical-like ZnO structures are obtained by varying the carbohydrate. The synthesized composites present good photocatalytic and antimicrobial activity.
