Increasing the activity of the Cu/CuAl2O4/Al2O3 catalyst for the RWGS through preserving the Cu2+ ions

Jeremy Luterbacher, Oliver Kröcher, Florent Emmanuel Héroguel, Alimohammad Bahmanpour, Yuan-Peng Du, Benjamin Pierre Le Monnier

Cu-Al spinet oxide is a highly active catalyst for CO2 conversion to CO. However, it suffers from low surface area. By depositing a silica layer, we protected the catalyst surface and preserved the Cu2+ ions during the calcination process. These ions form ...

Continuous hydrogenolysis of acetal-stabilized lignin in flow

Jeremy Luterbacher, Songlan Sun, Jean Thierry C Behaghel de Bueren, Florent Emmanuel Héroguel, Yuan-Peng Du, Wu Lan

Using acetal-stabilized lignin we performed a truly steady state continuous high-yielding lignin depolymerization (45% monophenolics using Ni/C), which offered a window into challenges and opportunities that will be faced when processing this feedstock. Wi ...

Post-synthesis deposition of mesoporous niobic acid with improved thermal stability by kinetically controlled sol–gel overcoating

Jeremy Luterbacher, Florent Emmanuel Héroguel, Yuan-Peng Du

Niobia is a well-known solid acid catalyst owing to its intrinsic Brønsted and Lewis acidity. However, catalyst development with this oxide has been limited by our ability to control its pore structure and thermal stability. Here we report a novel post-syn ...
