Tunable fabrication of Au-TiO2 bi-nanoparticles monolayer on graphene oxides

摘要

In this work, we have developed a facile and large-scale bottom-up approach to fabricate Au-TiO2 binanoparticles monolayer onto graphene oxides with controlled distribution. Fabrication pathways of such architecture are addressed. Interestingly, Au-TiO2 nanocrystals can be anchored and interweaved on the surface of GOs to increase the specific surface area and improve their stability. In principle, such GUS/Au-TiO2 NPs can be very promising for high performance photocatalysts and electrodes in energy storages. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
