RuCl3 Supported on N‐Doped Graphene as a Reusable Catalyst for the One‐Step Glucose Oxidation to Succinic Acid. Issue 17 (26th July 2017) - Rizescu, Cristina
Abstract: Impregnation of RuCl3 on N‐doped graphenes results in the formation of well‐dispersed, small ruthenium oxyhydroxide nanoparticles supported on N‐doped graphene that may exhibit high selectivity (87 %) for the conversion of glucose into succinic acid under wet oxidation conditions (160 °C, 18 atm O2 pressure). Ruthenium loading and N‐atom distribution on graphene influence the catalytic activity, the best performing catalyst having 1 wt. % Ru loading on a graphene having a large population of graphenic N atoms. The high catalytic selectivity to succinic acid was correlated with the presence of small ruthenium nanoparticles. The present catalyst improves the best one previously reported because it does not require the continuous addition of an excess of amine to reach high succinic acid selectivity and reusability. Abstract : That′s sweet ! Glucose is converted in 87 % selectivity to succinic acid under catalytic wet oxidation conditions using ruthenium supported on N‐containing graphene as a catalyst without the addition of amines as a co‐catalyst.
