Synthesis of Au@ZIF-8 single- or multi-core–shell structures for photocatalysis

Abstract

We explored the use of PVP-Au NPs as nucleation seeds for zeolitic imidazolate framework-8 (ZIF-8) to selectively synthesize Au@ZIF-8 single- or multi-core-shell structures by epitaxial growth or coalescence of nuclei. Photocatalytic oxidation of benzyl alcohol was studied based on LSPR-induced light absorption.
