Abstract

The invention discloses an alloy nano-tube and a preparation method thereof, which belong to the field of nanometer material. The alloy nano-tube is a solid solution, a metal compound or an amorphous state formed by two transition metal elements, namely A and B, wherein the A accounts for 15.3 to 86.4 percent of the total amount, and the B accounts for 13.6 to 84.7 percent of the total amount. The preparation method comprises the following steps: a formwork with a layer of gold or platinum film introduced into the back side is soaked in an electrolysis bath containing metal ion A and B, and is electrodeposited under certain voltage and current conditions to obtain a binary alloy nano-tube. Binary alloy nano-tubes with different diameters, different lengths and different components can be obtained by adopting formworks with nanochannels with different inner diameters, controlling the electrodeposition time and adjusting cathode current density. The binary alloy nano-tube has simple preparation process, mild reaction conditions, strong controllability and good application prospect.

Description

technical field [0001] The invention belongs to the field of nanometer materials, in particular to highly ordered and diameter-controllable metal alloy nanotube arrays and a preparation method thereof. Background technique [0002] Metal nanotubes have attracted extensive attention due to their importance in the basic research of low-dimensional physics and their future application prospects in the fields of ultra-large integrated circuits, single-electron devices, electroluminescence, chemical sensors, and perpendicular magnetic recording. A lot of research has been done on the synthesis of metal nanotubes, but there is no general method for the synthesis of metal nanotubes so far. In the current existing technology, there are physical methods for preparing nanotubes, which mainly include laser ablation method, evaporation condensation method, arc discharge method, etc.; chemical methods, mainly including chemical vapor deposition method, solution reaction method and templa...
