Au催化硝基化合物加氢反应的研究的开题报告 一、研究背景和意义 Nitro compounds are widely application in fields such as medicine, agriculture, and explosives etc. However, nitro compounds are often highly reactive and difficult to reduce. Catalytic hydrogenation is a promising method to reduce nitro compounds to amino compounds. The use of catalysts can improve the reaction rate and selectivity, and make the reaction milder and safer. Among the current catalysts, gold (Au) and its alloys, have been shown to have excellent catalytic activity in the reduction of nitro compounds, and have attracted extensive attention from researchers. 二、研究目的和内容 The aim of this research is to study the catalytic hydrogenation of nitro compounds using Au and Au-based catalysts. Specifically, the following aspects will be studied: 1. Synthesis and characterization of Au and Au-based catalysts. 2. Optimization of reaction conditions, including reaction temperature, pressure, and catalyst loading, etc. 3. Study on the catalytic activity and selectivity of the catalyst in the reduction of different types of nitro compounds. 4. Reaction mechanism study of nitro compounds hydrogenation. 三、研究方法 1. Synthesis and characterization of catalysts: Various Au-based catalysts, such as Au/TiO2, Au/Al2O3, Au/C, and Au/activated carbon, will be synthesized by impregnation method. The morphology and structure of the catalysts will be characterized by N2 adsorption-desorption, X-ray diffraction, transmission electron microscopy, and scanning electron microscopy. 2. Reaction conditions optimization: The effect of different reaction conditions, such as reaction temperature, pressure, H2/nitro compound ratios, and catalyst loading, will be studied by performing a series of reactions with different reaction conditions. 3. Catalytic activity and selectivity study: The catalytic activity and selectivity of the catalysts will be evaluated by monitoring the reaction progress by high-performance liquid chromatography and gas chromatography. 4.
