The invention discloses a method for preparing
molybdenum ditelluride nanotubes. The method comprises the following steps: 1) laying
molybdenum hexacarbonyl to the bottom of a
ceramic crucible, layinga
porous anodic aluminum oxide mold plate with an opening facing downwards on the
molybdenum hexacarbonyl, sealing the
ceramic crucible, putting into a tubular furnace, performing low-temperature sublimation deposition in the presence of a gas, and continuously performing heating
pyrolysis; 2) cooling the vacuum tubular furnace to the
room temperature, putting the mold plate with the opening facing downwards into a
ceramic crucible with
tellurium powder, sealing the ceramic crucible, heating in the presence of the gas, and enabling a
single substance, namely
tellurium, to react with a
metal,namely molybdenum, directly; 3) removing the excessive aluminum
oxide mold plate and excessive
tellurium by using a diluted acid solution, performing suction
filtration treatment, and
drying, therebyobtaining a finished product. The method disclosed by the invention is simple in step, free of environment
pollution and free of complex equipment, a molybdenum ditelluride
nanotube powder material prepared by using the method is good in size
controllability, good in
crystallinity and uniform in
nanotube wall and morphology, and thus the comprehensive properties of a finished product of the molybdenum ditelluride
nanotube powder material are greatly improved. The method is wide in applicability and beneficial to large-scale industrial production.
