A Precious Catalyst: Rhodium-Catalyzed Formic Acid Dehydrogenation in Water

The performance of rhodium complex [Cp*Rh(bis(pyrazol-1-yl)methane)Cl]Cl was evaluated for formic acid dehydrogenation in aqueous solution. Solid-state X-ray diffraction helped to confirm the catalyst structure. Multinuclear NMR spectroscopy was employed t ...

Homogeneous Catalytic Formic Acid Dehydrogenation in Aqueous Solution using Ruthenium Arene Phosphine Catalysts

Gabor Laurenczy, Cornel Fink, Lu Chen

In this work, we studied catalytic formic acid dehydrogenation with a homogeneous RAPTA type precatalyst in aqueous solution. The effects of an amino group, attached to the arene, and the impact of a second equivalent of 1,3,5‐triaza‐7‐phosphaadamantane (P ...

High-pressure NMR spectroscopic and calorimetric studies on formic acid dehydrogenation and carbon dioxide hydrogenation

Cornel Fink

Our current energy production is convenient and simple, but it is not sustainable. The negative impacts on our environment are omnipresent in the form of smog, extinction of species, and global warming. A major challenge of our generation is the transition ...

CO2 as hydrogen vector - Transition metal diamine catalysts for selective HCOOH dehydrogenation

Gabor Laurenczy, Cornel Fink

The homogeneous catalytic dehydrogenation of formic acid in aqueous solution provides an efficient in situ method for hydrogen production, under mild conditions, and at an adjustable rate. We synthesized a series of catalysts with the chemical formula [Cp* ...

Versatile palladium-catalyzed double carbonylation of aryl bromides

Paul Joseph Dyson, Gabor Laurenczy, Cornel Fink, Xinbang Wu

A versatile palladium-catalyzed double carbonylation of aryl bromides has been developed. Using Pd(OAc)2/BuPAd2 as the catalyst system and DBU as the base, under relatively low CO pressure, various a-ketoamides were produced in good yields. In order to get ...

An efficient Pt nanoparticle–ionic liquid system for the hydrodeoxygenation of bio-derived phenols under mild conditions

Paul Joseph Dyson, Gabor Laurenczy, Zhaofu Fei, Cornel Fink, Lu Chen

Platinum nanoparticles (NPs) were synthesized in situ in the ionic liquid (IL) [Emim]NTf2 (1-ethyl-3- methylimidazolium bis(trifluoromethylsulfonyl)imide) as well as in mixtures of [Emim]NTf2 with a second IL, Lewis acid or Brønsted acid, but in the absenc ...

Calorimetric and Spectroscopic Studies on the Solvation Energetics for H2 Storage in the CO2/HCOOH System

Gabor Laurenczy, Cornel Fink

Solvents play a crucial role in many chemical reactions and additives can be used to shift the reaction equilibrium. Herein we study the enthalpy of mixing for selected solvents (aqueous, organic) and basic additives (amines, aqueous KOH) when mixed with f ...

Hydrogen Storage in the Carbon Dioxide - Formic Acid Cycle

Gabor Laurenczy, Cornel Fink, Mickael Montandon-Clerc

This year Mankind will release about 39 Gt carbon dioxide into the earth's atmosphere, where it acts as a greenhouse gas. The chemical transformation of carbon dioxide into useful products becomes increasingly important, as the CO2 concentration in the atm ...
