Abstract Nano-sized catalytic sites can be synthesized using reverse micelles to systematically deposit active metal species onto catalyst supports. The size of these metallic sites is influenced by the synthesis conditions, namely the water to surfactant molar ratio, the surfactant concentrations, and the surfactant type. These parameters can be adjusted to create tunable micro-structures that are catalytically active for specific chemical reactions. From a literature search, the size of catalytic sites was compiled against their respective synthesis conditions. A regression analysis was performed to investigate which parameters had significant effects on the size of the catalytic site. Initial laboratory tests were then carried out using the regression results to develop nano-nickel sites deposited onto TiO2. According to the model, specific surfactant/solvent combinations (i.e. AOT/cyclohexane) and the water to surfactant molar ratio had profound impacts on the size of the produced catalytic site.

使用反胶束实现所需的纳米级催化活性位点的回归分析与实验室验证

摘要 纳米尺寸的催化位点可以使用反胶束合成，将活性金属物质系统地沉积到催化剂载体上。这些金属位点的大小受合成条件的影响，即水与表面活性剂的摩尔比、表面活性剂浓度和表面活性剂类型。可以调整这些参数以创建对特定化学反应具有催化活性的可调微结构。从文献检索中，催化位点的大小是根据它们各自的合成条件编制的。进行回归分析以研究哪些参数对催化位点的大小有显着影响。然后使用回归结果进行初步实验室测试，以开发沉积在 TiO2 上的纳米镍位点。根据模型，
