Abstract

Imogolite is a structurally microporous tubular clay comprising one-dimensional pore channels that are 0.8 – 1.2 nm in diameter, depending on composition. The microporous structure of natural and synthetic imogolite has been investigated by nitrogen adsorption as a function of outgassing temperature. A significant increase in adsorption at low relative pressure (P/P0 ∼ 10-6) after 275°C outgassing reflects a high concentration and narrow distribution of 0.8 – 0.9 nm diameter pores (i.e., the imogolite tubes) and supports the potential use of imogolite in inorganic membrane applications.
