Synthesis of Thiol Functionalized MOF-808 and its Efficiency for Mercury Removal.

A thiol-functionalized MOF-808 was produced and used to remove mercury by post-synthetic modification using 6-mercaponicotinic acid (6mna). Parent MOF-808 was impregnated for varied periods in the 6mna solution to create modified MOF-808 materials, known as MOF-808-6mna-x, where x refers to the impregnation time. Diffraction and several spectroscopic techniques were employed to quantify and confirm the coordination of 6mna into MOF-808 framework.

Capturing CO through High Surface Area Activated Carbon Derived from Seed Shells of Balanites Aegyptiaca.

Activated carbon is an attractive adsorbent for capturing various environmental pollutants, including CO. Herein, an optimal synthesis and impressive performance of activated carbon made from Balanites aegyptiaca (Desert date) seed shells is reported, which is an abundant agricultural waste in the Middle East and Africa. The synthesis route involved pretreating the biomass with KOH and heating it under a suitable temperature profile.
