| Summary: | 碩士 === 國立勤益科技大學 === 化工與材料工程系 === 104 === In the past two decades, the use of noble metallic nanoparticles have attracted extensive attention due to their optical and electronic propertiesand potential utility in catalysis,because the nanometal particles have a unique catalytic properties make it can be applied to chemical catalysts.
A novel Au/grpahene material as a catalyst for reduction of 4-nitrophenol has been studied in this article. Firstly, the aniline oligomer was been synthesized and used as a surfactant to modify graphene by π-π interaction. The amine group on the graphen will be absorbed gold nanoparticles to form a new catalyst. The uniform size distribution of Au nanoparticles, and the electron transfer from graphene to Au makes the novel Au/graphene as an efficient and reusable catalyst in the reduction of nitroaromatic compounds,it was demonstrated that Au /Oligoaniline /GO as a catalyst has excellent performance and stability for reduction 4-Nitrophenol(4-NP) to 4-Aminophenol(4-AP) within 3 minutes.
