Abstract

The present invention discloses process of preparing organic semiconductor compounded nanometer titania line with titania sol of anatase crystal. The process includes the following steps: 1. adding organic semiconductor into titania sol of anatase crystal through stirring to obtain organic semiconductor compounded titania sol; 2. soaking alumina template with nanometer pores inside the sol for filling the sol into the pore canals of the template, or setting the sol on one side of the alumina template and adding negative pressure other the other side to fill the sol into the pore canal of the template; 3. taking out the alumina template with nanometer pores and drying; and 4. and dissolving off the alumina template with nanometer pores with alkali or acid to obtain the organic semiconductor compounded nanometer titania line. The nanometer titania line thus prepared has high optical performance and high carrier transferring efficiency.

Description

Technical field

[0001] The invention relates to the field of nanometer and material science, in particular to a method for preparing organic semiconductor composite titanium oxide nanowires through a template at low temperature. Background technique

[0002] The semiconductor material titanium oxide has attracted great attention in various fields such as solar energy utilization, environmental purification, sensors, and catalysts. The use of porous alumina (AAO) template to prepare titanium oxide into nanowires or nanowire arrays can increase the specific surface area, increase the carrier transfer efficiency, prepare nano-prototype devices, and improve the integration of nano-components. Therefore, it is important significance.

[0003] Titanium dioxide nanowires have broad application prospects in gas sensors, humidity sensors, solar cells, nanoelectronic devices, lithium batteries, etc., but the existing preparation methods that are compatible with template methods such as sol...
