Preparation Of Platinum And Copper Nanowires And The Catalytic Application

Nanomaterial is referred to the metarial with at least one d imension in nanoscale（1 100 nm）. Compared with the macroscopic material, changing of size is also associated with the change of properties. Different from the bulk materials and the microscopic materials made up of atoms, nanomaterials possess some spec ial chemical and physical properties, such as mechanical, thermal, optical, and electrical performance. In mesoscopic nanometer system, it has been observed several new effects, small size effect, quantum size effect, surface effect and macroscopic quantum tunneling effect.Nanomaterials have smaller size and larger specific surface area, along with the difference of surface electron distribution and the differences between internal and external, which promotes the application in catalysis.This thesis mainly refers to the synthesis of noble metals platinum nanowires and the catalytic oxidation of amide, the synthesis of ultrathin copper nanow ires, copper nanowires catalyzed Click chemistry. The main research content is as follows:（1） Etching FePt nanowires with the mixture of acetic acid and hydrochloric acid to prepare the long, ultrathin, highly active Pt nanowires with diameter of 1 2 nm and length up to 2μm.（2） With the catalysis of the prepared Pt nanowires and oxidant tertiary butyl peroxide, we successfully one-step synthesized amides from aldehydes and amine s. We also expended the substrates and explored the reaction mechanism.（3） With CuCl₂ as raw materials, glucose as the reducing agent, hydrothermally synthesized ultrafine, neat Cu nanowires material and characterized.（4） With Cu nanowires as catalyst, acetylene compounds, sodium azide and bromide as raw materials, one-step synthesized 1,2,3-azoles and expended the substrates.
