Nano-sized mesoporous sodium iron hydroxyphosphate supported gold: an effective catalyst for the oxidation of sulfides†
Abstract
New nano-sized mesoporous sodium iron hydroxyphosphate (SIHP, Na4.55Fe(PO4)2H0.45O), synthesized by a microemulsion–hydrothermal synthesis method, with supported gold nanoparticles (AuNPs) could be a very effective catalyst for the selective oxidation of sulfides. The results showed that the SIHP material was an excellent catalyst support due to its special structure and the interactions between the AuNPs and the surface hydroxyl groups.
