Mesoporous titanium dioxide/anodic aluminum oxide heterogeneous nanochannel and preparation method thereof
The invention belongs to the field of intelligent nano-channels, and particularly relates to a mesoporous titanium dioxide/anodic aluminum oxide (MTI/AAO) heterogeneous nano-channel based on an interface super-assembly strategy and a preparation method of the mesoporous titanium dioxide/anodic aluminum oxide (MTI/AAO) heterogeneous nano-channel. According to the mesoporous titanium dioxide/anodic aluminum oxide heterogeneous nano-channel, tetraisopropyl titanate (TTIP) is used as a titanium source, a block copolymer P123 is used as a template agent, a titanium dioxide precursor solution and an oxygen bridge bond formed after hydroxyl on the surface of AAO are hydrolyzed are utilized, the AAO is used as a substrate, and the mesoporous titanium dioxide/anodic aluminum oxide heterogeneous nano-channel is prepared by means of a spin coating method. A layer of ultrathin, regular and ordered mesoporous titanium dioxide film with adjustable thickness and aperture is grown on an AAO substrate through an interface super-assembly and evaporation-induced self-assembly construction strategy. The MTI/AAO heterogeneous nano channel is regular in structure, adjustable in surface charge and good in photoelectric response and ion transport capacity. The invention not only provides a reliable technical support for the development of the intelligent nano channel, but also provides a new material for the photoelectric response field of the intelligent nano channel.
