Abstract

t. Two types of nanocomposites and nanoporous powders and related coatings were prepared by the sol-gel route. These silica-based materials contain dispersed reactive oxides, ZnO and ZnCr2O4, respectively. ExperimentsevidencedtheirabilityofreversiblechemisorptionofH2SasZnS.Theirattractiveporouscharacteristics (smallporesize ∼2–2.5nm,highspecificsurfacearea∼900–1100m2·g−1,highporosity∼50–60%)arenotsignificantlymodifiedduringthesuccessivetreatmentsofH2Schemisorptionandoxideregeneration.Thesepreliminary results encourage to pursue this study which aims at the preparation of nanofilters for the desulfurization of gas mixtures.
