The manuscript “A silica-based magnetic platform decorated with mixed ligand gold nanoparticles: A recyclable catalyst for esterification reactions” (Elif Ertem, Nerea Murillo-Cremaes, Randy Patrick Carney, Anna Laromaine, Emma-Rose Janeček, Anna Roig* and Francesco Stellaccia*; DOI: 10.1039/C6CC01146B) has been accepted in Chemical Communications.
This paper describes a novel and convenient synthetic strategy for the preparation of magnetically responsive silica nanospheres decorated with mixed ligand protected gold nanoparticles. Gold nanoparticles are attached to the silica surface via stable amide bond formation. The hierarchical nanospheres show promising results as a reusable and efficient catalyst for esterification reactions and they can be recovered through a simple magnetic separation.
