Metal oxide nanotube and process for production thereof

摘要

Spiral shaped fibers were utilized to prepare completely novel metal oxide nanotubes comprising solely metal oxides. The metal oxide nanotubes comprise solely a hollow cylinder shaped metal oxide which may contain hydroxyl groups constituting a double helix and having hole diameter distributions containing two peak hole diameters ranging from 1 to 2 nm and from 3 to 7 nm. The tubes may be obtained by forming spiral shaped fibers from a solution of compound 1 and compound 2 and using the fibers as a template for making the nanotubes. The hydrogen adsorption and storage capacity of the metal oxide nanotubes are extremely good.
