High-efficiency carbon dioxide reduction using catalytic nonthermal plasma desorption

Catalytic hydrogenation of carbon dioxide using Ir(III)-pincer complexes.

Catalytic hydrogenation of carbon dioxide in aqueous potassium hydroxide was performed using a newly synthesized isopropyl-substituted PNP-pincer iridium trihydride complex as a catalyst. Potassium formate was obtained with turnover numbers up to 3,500,000 and a turnover frequency of 150,000 h(-1), both of which are the highest values reported to date.

Selective catalytic reduction of sulfur dioxide by carbon monoxide over iron oxide supported on activated carbon

The selective reduction of sulfur dioxide with carbon monoxide to elemental sulfur was studied over ACsupported transition-metal oxide catalysts. According to the study, Fe2O3 /AC was the most active catalyst among the 4 AC-supported catalysts tested. By using Fe2O3 /AC, the best catalyst, when the feed conditions were properly optimized (CO/SO2 molar ratio = 2:1; sulfidation temperature, 400 ◦...

Catalytic Cyclocarbonylation in Compressed Carbon Dioxide: Pressure Influence of Carbon Monoxide and Carbon Dioxide

Among the current interests in organic synthesis are those reactions performing multiple C-C bond formation, in special when they undergo under catalytic conditions. Due to its properties, there is a growing interest on the use of compressed fluids (CF) as solvent media in catalytic processes. In this context, we present herein studies that aim to the development of a cleaner technology for the...
