Sulfonation of nanoporous activated carbon (NAC) was performed in the different ways available within the synthetic organic chemistry armory for preparing solid acid catalysts of isopropyl alcohol ...

Nanoporous activated carbon (NAC) beads that prepared by carbonization of microporous polymer 2,6-di-tert-butyl pyridine beads were subjected to bromination followed by amination to synthesize the ...

One of the major goals when creating new energy systems is to provide clean and affordable energy. Currently, there is an excessive increase in the cost of fossil fuels and natural gas because of increased energy consumption and the inability to meet demand. That is why it is necessary to find reliable renewable energy sources and processes that will produce energy materials without toxic by-products in order to preserve the environment and to ensuring sustainable development and a strong economy. From environmental safety reasons, this need has led to the development of the catalytic synthesis of energetic materials from greenhouse gases; in particular, this paper proposes an efficient approach to producing methane by hydrogenation of carbon dioxide over Co–Ni catalysts.

Halogenated activated carbons (AC–Hal, Hal = F, Br and Cl) used as precursors were functionalized with SO 3 H groups to prepare (AC–Hal–S) solid acid catalysts. ACs obtained were subjected to chemical and elemental analysis, characterized by miscellaneous physicochemical techniques and were tested in the propan-2-ol dehydration. The high catalytic activity of AC–Hal–S (Hal = F, Cl) is attributed to the presence of F and Cl affect on the catalysts performance and stability at the operation conditions.
