The interparticle coupling effect of gold nanoparticles in confined ordered mesopores enhances high temperature catalytic oxidation

Abstract

Based on the experimental results of selective cyclohexanol to cyclohexanone transformation, carbon monoxide total oxidation, and the surface enhanced Raman scattering mapping technique, we show here that the interparticle coupling effect of multiple AuNPs confined within the three dimensional ordered mesoporous scaffold of EP-FDU-12 not only improves their thermal stability but also enhances their catalytic oxidation properties operated at high temperatures.
