Abstract
Methods of purifying hydrogen-containing materials are described. The methods may include the steps of providing a purifier material comprising silica. The silica may be heated at temperature of about 100° C. or more in a dry atmosphere to form activated silica. The activated silica may be contacted with a starting hydrogen-containing material, where the activated silica reduces a concentration of one or more impurity from the starting hydrogen-containing material to form the purified hydrogen-containing material, and where the activated silica does not decompose the purified hydrogen-containing material.
