Incorporation of Graphene Oxide in Quantum Dot Sensitized Photocatalyst Based on ZnO Nanorods

Abstract

The novel efficient architecture of photocatalyst is fabricated by incorporating graphene oxide (GO) in quantum dots (QDs) sensitized ZnO nanorods and the photocatalytic properties for methyl orange (MO) degradation are investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-vis-NIR absorption spectroscopy. The results indicate that the incorporating of grapheme oxide is more favourable for the degradation. The improved photocatalytic properties can take several advantages given that the higher carrier mobility of GO which can reduce the recombination of carriers, and assembled quantum dots which can facilitate the absorption of solar light. The paper provides the clue to design the effective and easy recyclable photocatalyst.

Enhanced photovoltaic performance of inverted hybrid bulk-heterojunction solar cells using TiO 2 /reduced graphene oxide films as electron transport layers

“…For higher amounts of RGO, an increase in R s was observed due to the large resistance toward out-of-the plane conduction among RGO sheets. 54,55 The TiO 2 ∕RGO film thickness (see in Fig. 13 in Appendix) is also a determining factor for a solar cell.…”
