Heat- and Oxygen-Stable Biocatalyst for Hydrogen Production

Newly detected [FeFe]-hydrogenase from a thermophilic bacterium is not degraded by oxygen

15-May-2025 - In the absence of air, microorganisms produce hydrogen using an enzyme called [FeFe]-hydrogenase, one of the most efficient hydrogen-producing biocatalysts known and a promising tool for green hydrogen energy. However, these enzymes are rapidly destroyed when exposed to air, which has so far ...

The proportion of harmful substances in particulate matter is much higher than assumed

Measured from the air in real time

02-Apr-2025 - People breathing contaminated air over the course of years are at greater risk of developing numerous diseases. This is thought to be due to highly reactive components in particulate matter, which affect biological processes in the body. However, researchers from the University of Basel have now ...

Direct splitting: electrochemical process uses carbon dioxide to produce oxygen

27-Mar-2025 - To mitigate global climate change, emissions of the primary culprit, carbon dioxide, must be drastically reduced. A newly developed process helps solve this problem: CO2 is directly split electrochemically into carbon and oxygen. As a Chinese research team reports in the journal Angewandte ...

Progress Toward a New Generation of Rechargeable Batteries

Redox mediator improves performance and lifespan of Li-O2 batteries

29-Jan-2025 - Lithium–air batteries have the potential to outstrip conventional lithium-ion batteries by storing significantly more energy at the same weight. However, their high-performance values have thus far remained theoretical, and their lifespan remains too short. A Chinese team has now proposed ...

From soot particle filters to renewable fuels

Unravelling the chemical processes in soot particle filters reveals new ways to produce synthetic fuels

23-Jan-2025 - Carbon particles are present in many aspects of our daily lives. Soot, which consists of tiny carbon particles, is generated when energy sources such as oil or wood are not completely burned. Soot particle filters, in turn, remove the nanometer- to micrometer-sized particles from car exhaust ...

Green hydrogen: MXenes shows talent as catalyst for oxygen evolution

Catalysts based on MXenes are more stable and efficient than conventional catalysts: Investigations are now revealing the reasons for this

12-Sep-2024 - The MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalised, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitting. They are more stable and efficient than the ...
