Halloysite is a polytype of kaolinite with hollow nanotubular structure and many potential industrial or environmental applications. Natural halloysite is formed with a ~10Å basal spacing owing to a monolayer of interlayer H2O. Upon exposure to ambient humidity, most of the interlayer H2O is irreversibly lost and the basal spacing collapses to ~7Å. Some residual H2O in halloysite-(7Å) is observed at 3550 and 1650 cm-1 in the infrared spectra (“hole water”)
