Increased nickel exsolution from LaFe0.8Ni0.2O3 perovskite-derived CO2 methanation catalysts through strontium doping

Perovskite-derived Ni catalysts offer the remarkable benefit of redox stability that allows their regeneration after deactivation through poisoning or Ni particle growth. Here, the catalytic activity of LaFe0.8Ni0.2O3 towards CO2 methanation was improved b ...

Biomimetic Hydrogenation Catalyzed by a Manganese Model of [Fe]-Hydrogenase

Xile Hu, Huijie Pan

[Fe]‐hydrogenase is an efficient biological hydrogenation catalyst. Despite intense research, Fe complexes mimicking the active site of [Fe]‐hydrogenase have not achieved turnovers in hydrogenation reactions. Herein, we describe the design and development ...

A Bulky Chiral N‐Heterocyclic Carbene Nickel Catalyst Enables Enantioselective C−H Functionalizations of Indoles and Pyrroles

Nicolai Cramer, Daria Grosheva, Johannes Diesel, Shota Kodama

An enantioselective nickel(0)-catalyzedC  Hfunc- tionalization of indoles and pyrroles that does not require the typical Lewis basic directing groups is disclosed. The reaction provides access to valuable tetrahydropyridoindoles and tetrahydroindolizines ...

Segregation of Nickel/Iron Bimetallic Particles from Lanthanum Doped Strontium Titanates to Improve Sulfur Stability of Solid Oxide Fuel Cell Anodes

Davide Ferri, Oliver Kröcher, Andre Heel

Perovskite derived Ni catalysts offer the remarkable benefit of regeneration after catalyst poisoning or Ni particle growth through the reversible segregation of Ni from the perovskite-type oxide host. Although this property allows for repeated catalyst re ...

Effect of SiO2 on co-impregnated V2O5/WO3/TiO2 catalysts for the selective catalytic reduction of NO with NH3

Davide Ferri, Oliver Kröcher, Adrian Marberger

Co-impregnation of vanadia and tungsta on titania produced highly active catalysts for the reduction of nitrogen oxides with ammonia but showed aging tendencies at temperatures around 600 degrees C. In order to preserve their low temperature activity after ...

Metal-Sulfide Catalysts Derived from Lignosulfonate and their Efficient Use in Hydrogenolysis

Paul Joseph Dyson, Xile Hu, Zhaofu Fei, Antoine Philippe Van Muyden, Xiang Li, Lichen Bai, Xinjiang Cui, Sijie Liu

Catalytic lignosulfonate valorization is hampered by the in situ liberation of sulfur that ultimately poisons the catalyst. To overcome this limitation, metal sulfide catalysts were developed that are able to cleave the C-O bonds of lignosulfonate and are ...

Chiral N-Heterocyclic Carbene Ligands for Asymmetric Catalysis

Johannes Diesel

N-Heterocyclic carbenes (NHCs) are the ligands of choice in a large variety of transformations entailing different transition metals. However, the number of chiral NHCs suitable as stereocontrolling ligands in asymmetric catalysis remains limited. In parti ...

Manganese-mediated reductive amidation of esters with nitroarenes

Xile Hu, Peng Wang, Chi Wai Cheung, Ning Shen

Amides are ubiquitous molecules in nature and in synthetic chemistry. Here we report a convenient and efficient method to synthesize N-aryl amides via amidation of esters with nitroarenes. In the presence of manganese metal, this amidation proceeded smooth ...
