Rusting iron can be its own worst enemy

Simulations show iron catalyzes corrosion in 'inert' carbon dioxide

26-Jan-2022

Iron that rusts in water theoretically shouldn’t corrode in contact with an “inert”supercritical fluidof carbon dioxide. But it does. The reason has eluded materials scientists to now, but a team at Rice University has a theory that could contribute to new strategies to protect iron from the ...

Turning harmful carbon dioxide into useful chemicals

Inspired by nature: Electro-biocatalytic CO₂ fixing replaces fossil resources

14-Jan-2022

Making important raw materials for fine chemicals out of carbon dioxide really works. As part of the Max Planck collaborative project eBioCO2n, a team of researchers from Fraunhofer IGB have successfully performed a first ever fixation of CO2 via a multi-enzyme enzyme reaction driven by ...

The next big thing: A new technology for directly converting carbon dioxide into pure formic acid

Novel electrochemical device based on solid-state electrolyte

05-Jan-2022

Anthropogenic emissions of carbon dioxide bring a series of climatic and environmental problems including global warming. Artificially upcycling of carbon dioxide into value-added fuels and chemicals, powered by "green electricity" of renewable energy, provides an elegant route to close the ...

From the oilfield to the lab

A special microbe turns oil into gases all by itself

03-Jan-2022

Microorganisms can convert oil into natural gas, i.e. methane. Until recently, it was thought that this conversion was only possible through the cooperation of different organisms. In 2019, Rafael Laso-Pérez and Gunter Wegener from the Max Planck Institute for Marine Microbiology suggested that a ...

Novel electrocatalyst boosts synthesis of urea from CO2 and N2

20-Dec-2021

A research team led by Prof. ZHANG Guangjin from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences has fabricated a novel InOOH electrocatalyst with unique frustrated Lewis pairs (FLPs) for efficient urea synthesis at ambient conditions. The industrial process of ...

Energy Conversion: Make carbonate not carbon dioxide

Scientists developed a technique to avoid CO2 in energy conversion processes with carbon-containing fuels

19-Nov-2021

Nature knows several ways how to capture carbon dioxide (CO2). The most prominent one is photosynthesis, where sun light is used to fix CO2 into biomass. Nowadays, research groups around the world try hard to mimic this process and to realize artificial photosynthesis. The ultimate goal is to ...

Methane from Carbon Dioxide

Efficient catalyst for the light-driven methanation of CO2

19-Nov-2021

Recycling carbon dioxide (CO2), especially through conversion to methane (CH4), is compelling while anthropogenic CO2 emissions are still rising. A useful process for this transformation is photothermal methanation, in which CO2 and hydrogen are catalytically converted into CH4 and water upon ...

Liquid Fuels from Carbon Dioxide

Electrocatalyst converts CO2 into multicarbon products

18-Nov-2021

A new electrocatalyst called a-CuTi@Cu converts carbon dioxide (CO2 ) into liquid fuels. As reported by a team of Chinese researchers in the journal Angewandte Chemie, active copper centered on an amorphous copper/titanium alloy produces ethanol, acetone, and n-butanol with high efficiency. Most ...

Circular economy for CO2

18-Nov-2021

To establish a carbon-neutral circular economy in the future, technologies are needed that use carbon dioxide as a raw material. In the form of formate, CO2 can be metabolised by certain bacteria. Acetogens are a group of bacteria that can metabolise formate. For example, they form acetic acid – ...

More power – less carbon dioxide

Success at the Carbon Removal Student Competition

16-Nov-2021

Biogas is an important factor in the implementation of the energy transition. But there is room for improvement in the efficiency of these facilities. Researchers at the Technical University of Munich (TUM) have developed a plant concept that combines greater power output with a smaller carbon ...
