Synthesis and Physicochemical Characterization of Surface-functionalized ZnO Nanoparticles

Abstract

The effect of synthesis parameters on the dimensions and morphology of ZnO NPs will be studied in this work, together with their methodical characterization for the assessment of their structural, morphological and optical characteristics. Zinc oxide nanoparticles were synthesized via chemical precipitation method by employing different reaction precursors and experimental conditions, in order to conveniently tune the band gap energy values of the prepared samples. Further, the as-prepared nanoparticles will be surface modified with silane derivatives for subsequent integration in polymeric supports, with the goal of avoiding nanoparticles agglomeration, translating photocatalytic activity towards visible light, and facilitating catalyst reusability/recovery after photocatalytic cycles.
