Hybrid composites of MIL-101(Cr) and Nanoporous Graphene with ratios in the range of 10-50% were prepared via hydrothermal synthesis method. This study deals with an experimental investigation on selective oxidation of H2S into elemental sulfur in the range of 200-270 degrees C, the catalyst activity and selectivity toward sulfur was studied. High-temperature reactor tests indicated that the MIL-101(Cr)-NPG50-Mo could be a promising candidate with conversion and selectivity of 100% and 99.5% at 200 degrees C. The MIL-101(Cr)-NPG50-Mo stability showed there were not any significant changes in physical properties, the activity was evaluated after 20 h which was completely stable without any changes.
