Abstract

Imogolite is a structurally microporous tubular clay comprising one-dimensional pore channels that are ∼1 nm in diameter. In addition to its novel tubular morphology, a notable structural characteristic of imogolite is its occurrence in paracrystalline tube bundles in which the individual tubes are close-packed with their axes in parallel alignment. We have developed a technique that aligns and tightly packs the tube bundles over macroscopic dimensions, in a manner analogous to the alignment and packing of the individual imogolite tubes within the bundles. This extends the range of imogolite paracrystallinity, effectively eliminating mesoporosity and nontubular phases.
