Start-ups made carbon-neutral fuels and turning carbon dioxide into stone
More and more ETH Zurich researchers are taking the plunge into entrepreneurship. By launching spin-offs, they hope to turn their lab findings into solutions that can help stem the rise in atmospheric carbon dioxide. There is no shortage of evidence for what the Fifth Assessment Report of the ...
Free electron laser study sheds light on the mechanism and timescale of the photocatalytic oxidation of carbon monoxide on titanium oxide
An international team of scientists have studied, for the first time, the light induced oxidation of carbon monoxide (CO) to carbon dioxide (CO2) on the surface of an oxide photocatalyst in real-time using the soft X-ray free-electron laser FLASH combined with theoretical calculations. According ...
New method could potentially reduce dioxide emission into the atmosphere and slash costs of chemical manufacturing
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have demonstrated a room-temperature method that could significantly reduce carbon dioxide levels in fossil-fuel power plant exhaust, one of the main sources of carbon emissions in the ...
The separation process is both energy efficient and cost-effective
Chemists at the University of Bayreuth have developed a material that could well make an important contribution to climate protection and sustainable industrial production. With this material, the greenhouse gas carbon dioxide (CO₂) can be specifically separated from industrial waste gases, ...
Combining solar-harvesting materials with carbon-dioxide–consuming microbes could be an efficient way to generate clean fuels
Semiconductive photocatalysts that efficiently absorb solar energy could help reduce the energy required to drive a bioelectrochemical process that converts CO2 emissions into valuable chemicals, KAUST researchers have shown. Recycling CO2 could simultaneously reduce carbon emissions into the ...
Promising way to to transform ethylene production into a greener industry
A research team from Caltech and the UCLA Samueli School of Engineering has demonstrated a promising way to efficiently convert carbon dioxide into ethylene -- an important chemical used to produce plastics, solvents, cosmetics and other important products globally. The scientists developed ...
Evonik and Siemens Energy put pilot plant into operations
Evonik and Siemens Energy commissioned a pilot plant sponsored by the German Federal Ministry of Education and Research (BMBF) that uses carbon dioxide and water to produce chemicals. The necessary energy is supplied by electricity from renewable sources. The pilot plant is located in Marl, in ...
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 ...
