Novel catalytic process for converting CO2 into valuable chemical intermediates in the form of cyclic carbonates
Carbon dioxide (CO2) is not just an undesirable greenhouse gas, it is also an interesting source of raw materials that are valuable and can be recycled sustainably. In the journal Angewandte Chemie, Spanish researchers have now introduced a novel catalytic process for convertingCO2 into valuable ...
Significant step toward achieving artificial photosynthesis
Researchers have developed a standalone device that converts sunlight, carbon dioxide and water into a carbon-neutral fuel, without requiring any additional components or electricity. The device, developed by a team from the University of Cambridge, is a significant step toward achieving ...
Value creation by combining electrochemistry with biotechnology
Time for climate protection is pressing. One approach to tackle this challenge is to use the greenhouse gas CO2 as a raw material for chemicals. To this end, the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB, together with partners from science and industry, has pursued a ...
Ionic liquids help to understand the electrocatalytic conversion of CO₂
The conversion of carbon dioxide into hydrocarbons and other basic chemicals is important if we are to have a sustainable economy in the future. Researchers at the TU Darmstadt and the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy have now decoded major steps in electrochemical ...
By efficiently converting CO2 into complex hydrocarbon products, a new catalyst could potentially aid in large-scale efforts to recycle excess carbon dioxide
As levels of atmospheric carbon dioxide continue to climb, scientists are looking for new ways of breaking down CO2 molecules to make useful carbon-based fuels, chemicals and other products. Now, a team of Brown University researchers has found a way to fine-tune a copper catalyst to produce ...
New electrocatalyst efficiently converts carbon dioxide into ethanol
Catalysts speed up chemical reactions and form the backbone of many industrial processes. For example, they are essential in transforming heavy oil into gasoline or jet fuel. Today, catalysts are involved in over 80 percent of all manufactured products. A research team, led by the U.S. Department ...
Solve two problems at one stroke
Solid acids are amongst the most essential heterogeneous catalysts, which have the potential to replace environmentally harmful liquid acids, in some of the most important processes, such as hydrocarbon cracking, alkylation, as well as plastic waste degradation and carbon dioxide to fuel ...
Encapsulating multiple molecular catalysts in nanoporous metal-organic frameworks central to efficient transformation
Converting carbon dioxide to methanol, a potentially renewable alternative fuel, offers an opportunity to simultaneously form an alternative fuel and cut down on carbon dioxide emissions. Inspired by naturally occurring processes, a team of Boston College chemists used a multi-catalyst system to ...
Unusual nanoparticles could could be useful for environmental cleanups, sensors, electronic devices and solar cells
Imagine tiny crystals that "blink" like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels. A Rutgers-led team has created ultra-small titanium dioxide crystals that exhibit unusual "blinking" behavior and may help to produce methane and other fuels, according to ...
Polyimide membranes for the purification of natural gas
Natural gas that contains larger amounts of hydrogen sulfide (H2S) and carbon dioxide (CO2) is termed sour gas. Before it can enter a pipeline, it must be “sweetened” by removal of its acidic impurities. Through fine tuning of the ratios of two molecular components, it is possible to produce ...
