Hydrogen occluded in sulfide catalysts: Evidence from the temperature programmed heating technique
Strongly bonded hydrogen is found in alumina supported sulfide Co, Ni, Mo, (Co, Mo) and (Ni, Mo) catalysts. This hydrogen is desorbed from the catalysts in the temperature range of 500-750degreesC and seems to be occluded in the corresponding sulfide matrix. Possible sites of its localization in the sulfide crystal lattice are discussed.
