Abstract
Mass spectra showed that H2 evolved on vacuum heating of kaolinites, halloysite, and sepiolite but not on vacuum heating of the montmorillonite samples studied. Release of H2 occurred during clay dehydroxylation, but reached its maximum at a higher temperature. It was independent of the amount of Fe2+ or Fe3+ present in the clay. -Authors
