Metal organic framework derived NaCo_xO_y for room temperature hydrogen sulfide removal.

ABSTRACT: Novel NaCo_xO_y adsorbents were fabricated by air calcination of (Na,Co)-organic frameworks at 700 °C. The NaCo_xO_y crystallized as hexagonal microsheets of 100-200 nm thickness with the presence of some polyhedral nanocrystals. The surface area was in the range of 1.15-1.90 m² g^-1. X-ray photoelectron spectroscopy (XPS) analysis confirmed Co²⁺ and Co³⁺ sites in MOFs, which were preserved in NaCo_xO_y. The synthesized adsorbents were studied for room-temperature H₂S removal in both dry and moist conditions. NaCo_xO_y adsorbents were found ~ 80 times better than the MOF precursors. The maximum adsorption capacity of 168.2 mg g^-1 was recorded for
