Abstract

We demonstrated a simple, in situ reduction route to the synthesis of two-dimensional graphene oxide/SiO(2) (GSCN) hybrid nanostructures consisting of Au nanoparticles (Au NPs) supported on the both sides of GSCN. The as-prepared GSCN/Au NPs hybrid nanomaterials exhibited good catalytic activity for the reduction of 4-nitrophenol. This approach provided a useful platform based on GO hybrid nanomaterials for the fabrication of GSCN/Au NPs hybrid nanomaterials, which could be very useful in catalytic applications.

摘要

我们展示了一种简单的原位还原方法，用于合成二维氧化石墨烯/二氧化硅（GSCN）杂化纳米结构，该结构由负载在 GSCN 两侧的金纳米颗粒（Au NPs）组成。所制备的 GSCN/Au NPs 杂化纳米材料对 4-硝基苯酚的还原表现出良好的催化活性。该方法为制备 GSCN/Au NPs 杂化纳米材料提供了一个基于 GO 杂化纳米材料的有用平台，在催化应用中可能非常有用。
