Operando Observation of (Bi)carbonate Precipitation during Electrochemical CO2 Reduction in Strongly Acidic Electrolytes

Corsin Battaglia, Nukorn Plainpan, Alessandro Senocrate

Precipitation of (bi)carbonate salts during the electrochemical CO2 reduction (CO2RR) has been identified as a major cause of degradation and one of the main challenges to be overcome before implementing this technology on the industrial scale. Recently, t ...

Toward Sustainable and Cost-Effective CO2 Conversion Processes to Propylene Carbonate Based on Ionic Liquids

Elia Mercedes Ruiz Pachon

The use of ionic liquids (ILs) for CO2 capture and utilization into a valuable product is attracting interest even though literature evaluating their sustainability is scarce. A liquid-liquid extraction (LLE)-based separation is recently proposed as an alt ...

Method and system for producing a carbonate-containing species-rich, nitrogen-containing species-free solution

Lyesse Laloui, Dimitrios Terzis

A method for producing a carbonate-containing species-rich, nitrogen-containing species-free solution from a urea-rich solution is proposed. The method comprising the steps of: providing a first reservoir comprising a first mixture including urea and a cat ...

Catalyst design for C-O bond hydrogenolysis of renewable materials.

Antoine Philippe Van Muyden

Anthropogenic carbon dioxide emissions leading to climate change require to use of renewable carbon sources such as CO2 and biomass which differ from fossil resources by having a higher number of oxygen atoms. Therefore, catalytic C-O bond cleavage will pl ...

Copper battery for heat to power conversion and energy storage

Sunny Isaïe Maye

An important part of the electricity production relies on heat conversion. Indeed power plants burn fuels like natural gas, coal or use nuclear fission to produce heat that can be transformed into electricity through a thermodynamic cycle and the mechanica ...

Indirect CO2 Methanation: Hydrogenolysis of Cyclic Carbonates Catalyzed by Ru-Modified Zeolite Produces Methane and Diols

Paul Joseph Dyson, Felix Daniel Bobbink, Antoine Philippe Van Muyden, Wei-Tse Lee, Zhangjun Huang

We report a ruthenium‐modified zeolite which efficiently transforms propylene carbonate to propylene glycol and methane, under solvent‐free conditions. The catalyst achieved high product selectivity and no significant ageing effect was observed after multi ...

Palladium-Catalyzed Carboxy-Alkynylation of Propargylic Amines Using Carbonate Salts as Carbon Dioxide Source

Jérôme Waser, Phillip Gulliver Dominic Greenwood

A palladium-catalyzed multicomponent reaction of propargylic amines, alkynyl bromides and cesium hydrogen carbonate to access oxazolidinones is reported. In contrast to previous reports, only a slight excess of cesium hydrogen carbonate is used as a surrog ...

The role of malachite nanorods for the electrochemical reduction of CO2 to C-2 hydrocarbons

Emad Oveisi, Jie Zhang, Kun Zhao, Mariana Spodaryk

The electrochemical reduction of CO2 to higher hydrocarbons is a very challenging process that has high potential for the storage of large amounts of renewable energy with a high gravimetric and volumetric energy density. The distribution of hydrocarbons f ...

En route to CO2-containing renewable materials: catalytic synthesis of polycarbonates and non-isocyanate polyhydroxyurethanes derived from cyclic carbonates

Paul Joseph Dyson, Felix Daniel Bobbink, Antoine Philippe Van Muyden

Combining CO2-chemistry with biomass conversion allows renewable polymeric materials including polycarbonates and polyhydroxyurethanes (PHUs) to be generated. The demand for robust materials with modular properties that can be prepared on an industrial sca ...

Solvent effect in photo-ionic cells

Hubert Girault, Pekka Eero Peljo, Elena Vladimirova

Photo-ionic cells convert solar energy into redox fuels. Unlike in photovoltaic devices where the photo-induced charge transfer reactions occur at an electrode, the photoreaction takes place in one bulk solution of a biphasic liquid-liquid system, and the ...
