The dilemma between acid and base catalysis in the synthesis of benzimidazole from o-phenylenediamine and carbon dioxide

Paul Joseph Dyson, Simon Nussbaum, Martin Hulla, Alexy Robert Bonnin

The tandem synthesis of benzimidazole and other azoles can be achived by the N-formylation of ortho-substituted anilines followed by a cyclization reaction. However, CO2-based N-formylations with hydrosilane reducing agents are base catalyzed whereas the c ...

Labor division in engineered cross-kingdom consortia: Consolidated bioprocessing of lignocellulosic biomass to carboxylic acids

Robert Lawrence Shahab

Lignocellulose is a renewable source of fixed carbon and a promising substrate for the production of chemicals and fuels in second generation biorefineries. In this thesis, we engineered artificial microbial consortia for consolidated bioprocessing (CBP) o ...

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 ...

Hydrothermally Stable Sulfonated Carbons as Solid Acid Catalysts for the Hydrolysis of Lignocellulose

David Ferdinand Scholz

The recycling of homogeneous acids imposes great challenges to the feasibility of lignocellulose hydrolysis processes. Although heterogeneous catalysts would offer a perspective to circumvent these challenges, conventional solid acids are instable under th ...

Highly Selective Oxidation and Depolymerization of α,γ-Diol Protected Lignin

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Wu Lan

Lignin oxidation offers a potential sustainable pathway to oxygenated aromatic molecules. However, current methods that use real lignin tend to have low selectivity and a yield that is limited by lignin degradation during its extraction. We developed stoic ...

Hydrogen storage in the carbon dioxide/formic acid system, using homogeneous iron(II)-phosphine catalysts in aqueous solution

Mickael Montandon-Clerc

The valorization of carbon dioxide and its transformation into useful chemicals is essential as mankind consumes more and more fossil fuels, thus producing equivalent wastes. The storage of hydrogen, a promising energy carrier, is also of great interest in ...

Additive free, room temperature direct homogeneous catalytic carbon dioxide hydrogenation in aqueous solution using an iron(II) phosphine catalyst

Gabor Laurenczy, Mickael Montandon-Clerc

The negative consequences of the global warming require an important reduction of CO2 emission; and the valorization of the carbon dioxide, its transformation into useful chemicals is essential. We present here our studies on the direct CO2 hydrogenation r ...

Development of heterogeneous catalytic systems for the transformation of carbon dioxide to methanol under mild conditions.

Aswin Gopakumar

Rising level of carbon dioxide (CO2) is a significant contributor to global warming and poses a major concern in modern society and environment. Anthropogenic activities such as fossil fuel combustion, cement production and deforestation are the primary ca ...

Recent progress for reversible homogeneous catalytic hydrogen storage in formic acid and in methanol

Gabor Laurenczy, Matthias Beller

Development of technologies using hydrogen as an energy carrier instead of fossil fuels is strongly required today. Especially, new, reversible, sustainable hydrogen storage technologies have received increasing attention. Formic acid (FA) and methanol (CH ...

Homogeneous Catalysis for Sustainable Hydrogen Storage in Formic Acid and Alcohols

Paul Joseph Dyson, Gabor Laurenczy, Katerina Stefania Sordakis, Matthias Beller

Hydrogen gas is a storable form of chemical energy that could complement intermittent renewable energy conversion. One of the main disadvantages of hydrogen gas arises from its low density, and therefore, efficient handling and storage methods are key fact ...
