From a greenhouse gas to an industrial raw material
06-Dec-2022
Rather than being released into the atmosphere and exacerbating the problem of climate change, CO2 can also be used as a raw material for substances required in industrial processes, such as formic acid or methanol. The conversion of CO2 has already been investigated in detail in laboratory ...
Fertilizing the ocean to store carbon dioxide
Iron-based fertilizer, engineered into nanoparticles, could help store excess carbon dioxide in the ocean
01-Dec-2022
The urgent need to remove excess carbon dioxide from Earth’s environment could include enlisting some of our planet’s smallest inhabitants, according to an international research team led by Michael Hochella of the Department of Energy’s Pacific Northwest National Laboratory. Hochella and his ...
New technology creates carbon neutral chemicals out of thin air
“Capturing CO2 from the surrounding air and directly converting it into useful products is exactly what we need to approach carbon neutrality in the chemicals sector"
14-Nov-2022
It is possible to capture carbon dioxide (CO2) from the surrounding atmosphere and repurpose it into useful chemicals usually made from fossil fuels, according to a study from the University of Surrey. The technology could allow scientists to both capture CO2 and transform it into useful ...
Natural CO2 reduction implemented faster and with less risk than high-tech approaches
Researchers have identified the approaches with the highest potential for carbon removal in Germany
10-Nov-2022
Carbon dioxide can be removed from the atmosphere by natural or technical means. Natural sinks such as peatlands can be restored, and innovative technologies already exist to extract carbon from the air. Researchers from the Helmholtz Climate Initiative's Net Zero 2050 Cluster have identified the ...
Audi and Krajete Filter CO₂ Out of the Air
Filter more CO₂ in less time thanks to the new direct air capturing method
02-Nov-2022
AUDI AG and the Linz-based green tech company Krajete GmbH are jointly developing new technologies for filtering emissions from ambient air. In addition to robust adsorber materials, these so-called direct air capturing technologies (DAC) are based, above all, on innovative processes. They make ...
Getting it to stick: Grabbing CO₂ out of the air
Direct air capture is hard to do - Pitt researchers are designing new materials that selectively catch carbon dioxide in the atmosphere
13-Oct-2022
Direct air capture may be key to saving Earth from the effects of climate change, but there’s a catch: It’s really hard to do. Direct air capture (DAC) technologies are designed to remove carbon dioxide from the air, although there’s still a lot of room for improvement in DAC materials. Other ...
International research project achieves record in converting carbon dioxide into fuels
Artificial leaf
11-Oct-2022
In an international research project involving the Technische Universität Ilmenau, scientists have succeeded in developing a sunlight-powered device that converts carbon dioxide directly into usable fuels with an efficiency of over five percent. This brings closer the goal of not only eliminating ...
On-site reactors could affordably turn CO₂ into valuable chemicals
“I’m excited by the potential of this technology”
10-Oct-2022
New technology developed at the University of Waterloo could make a significant difference in the fight against climate change by affordably converting harmful carbon dioxide (CO2) into fuels and other valuable chemicals on an industrial scale. Outlined in astudypublished in the journal Nature ...
Wrapping of nanosize copper cubes can help convert carbon dioxide into other chemicals
26-Sep-2022
Researchers found a new way to reduce carbon dioxide (CO2) emissions by wrapping copper nanocubes with an organic layer, solving instability and selectivity problems with copper nanocubes in catalysis, and improving how this electrocatalyst converts CO2 into organic molecules. As the need to ...
Fuel from a Greenhouse Gas
Single gold atoms catalyze the selective methanization of carbon dioxide
15-Sep-2022
One step toward carbon dioxide (CO2) neutrality and the mitigation of both the greenhouse effect and the energy crisis would be to convert CO2 into hydrocarbon-based fuels like methane using light. In the journal Angewandte Chemie, a Chinese research team has introduced a highly effective ...
