Application of Prussian Blue Analogue‐Derived Mn−Co Catalysts in the Hydrogenation of CO to Higher Alcohols

Abstract: MnxCo3‐x[Co(CN)6]2 Prussian blue analogues were synthesized with Mn : Co ratios in the range from 7 : 10 to 1 : 11 and pyrolyzed at 600 °C to obtain a highly nitrogen‐ and oxygen‐functionalized carbon matrix with embedded reduced Mn and Co species. These catalyst precursors were applied in the CO hydrogenation to higher alcohols at 260 °C and a pressure of 60 bar using a H2/CO ratio of 1. Metallic Co0 formed during pyrolysis was partially transformed into Co2C under reaction conditions. With increasing Co cont… Show more

“…16 According to the proposed reaction network, olefin hydration to secondary alcohols is an essential reaction mechanism for HAS over PBA-based catalysts. 4 Furthermore, a high CO 2 selectivity was observed for all investigated catalysts due to the WGSR. This was rather unexpected, because these Cu-free catalysts had been investigated with the goal to lower the CO 2 selectivity.…”

“…Both reactions are followed by hydrogenation to the corresponding long-chain alcohol (eqn (6) and (8)). 4,12–14 H 3 COH + CO → H 3 CCOOHBoth acetic acid and propionaldehyde have been observed in the obtained chromatograms while analyzing the effluent with a customized gas chromatographic (GC) application. Furthermore, the product gas stream was collected in a cooling trap and investigated by GC-MS supporting these mechanisms.…”
