Vertically aligned gold nanomushrooms on graphene oxide sheets as multifunctional nanocomposites with enhanced catalytic, photothermal and SERS properties†
Abstract
A novel and simple strategy for preparing vertically aligned gold nanomushrooms (AuNMs) on graphene oxide (GO) has been developed. The as-prepared GO/AuNM nanocomposites have been successfully applied in the catalytical organic transformation, photothermal ablation of bacteria and SERS detection.
