Involvement of support hydrogen in the H2-D2 isotopic exchange on sulfide catalysts
Studies in Surface Science and Catalysis（2001）
摘要
HD isotopic exchange experiments carried out over sulfided catalysts showed that part of the exchangeable hydrogen measured by isotopic dilution came from the support and depended on the pretreatment conditions. This hydrogen was essentially present as H 2 S adsorbed on the alumina support. D 2 (and D 2 S) adsorption followed by FTIR confirmed the involvement of support hydrogen.
