[Abstract]:Nanomaterials have attracted the attention of many researchers because of their excellent performance. Soft template method has been widely used in various methods of preparing nano-materials. This method not only can effectively control the morphology and size of nano-materials, but also can produce nano-materials with special shape because of the kinetic properties of the template itself. PD has a very important application in the field of catalysis. A series of Pd and its composite nano-materials have been prepared and widely used in various catalytic reactions. In this paper, many kinds of high performance Pd and its composite nano-materials were prepared by soft template method, and their catalytic properties were studied in detail. This paper mainly includes the following three parts: 1. Pd hollow nanospheres were successfully prepared by one-step soft template method using Rhodamine B (RB) / Na2PdCl4 RB-PdCl42- complex formed by electrostatic interaction as sacrificial template and NaBH4 as reducing agent at room temperature. It was used for electrocatalytic oxidation of formic acid and methanol. 2. Using RB-PdCl42- complex as sacrificial template and EDOT monomer as reducing agent, PEDOT/Pd composite hollow nanospheres were prepared by one-step method through the redox reaction between the two under the condition of 80 擄C. It was used in the catalytic reaction of peroxidase-like enzyme. 3. A layered (CTA) 2PdBr4 complex formed by electrostatic interaction between cetyltrimethylammonium bromide (CTAB) and Na2PdCl4 was used as a sacrificial template. At 90 擄C, a one-step redox reaction between the template and the polymer monomer was carried out. The conductive polymer / Pd composite nano-ring was successfully prepared and the catalytic performance of polypyrrole (PPy) / Pd composite nano-ring p-nitrophenol reduction was studied in detail.
