Bio solar cell produces hydrogen

Modular character allows multiple applications

27-Sep-2018

An international team of researchers has combined molecular building blocks from plants and microorganisms in a bio solar cell so that they could use light energy to directly produce hydrogen. This combination does not occur like this in nature: although plants can use light energy to convert ...

Greater than the sum of its parts

20-Sep-2018

When it comes to designing and optimizing mechanical systems, scientists understand the physical laws surrounding them well enough to create computer models that can predict their properties and behavior. However, scientists who are working to design better electrochemical systems, such as ...

Improved understanding of industrial electrode processes

The findings could help save carbon dioxide in the future

24-Aug-2018

In the industrial production of chlorine, recently special electrodes have been introduced, which consume much less current than conventional systems. The method requires oxygen which is introduced into hot, highly concentrated sodium hydroxide solution, in which it is poorly soluble. It is still ...

Liquid battery could lead to flexible energy storage

15-Aug-2018

A new type of energy storage system could revolutionise energy storage and drop the charging time of electric cars from hours to seconds. In a new paper, chemists from the University of Glasgow discuss how they developed a flow battery system using a nano-molecule that can store electric power ...

Sustainable plastics - with hydrogen as byproduct

New catalyst with a dual function

25-Jul-2018

Plastic production with this catalyst would be sustainable and would also enable the creation of hydrogen as a potential energy source. Chemists at Ruhr-Universität Bochum (RUB) have developed a new, low-cost catalyst for plastic production. It turns a biorefinery product into a starting material ...

Electrochemically-produced ammonia could revolutionize food production

11-Jul-2018

Steven McIntosh wants to transform the way ammonia is produced. He hopes to create a viable alternative to the conventional method, which uses massive amounts of energy and emits harmful carbon dioxide. He's exploring a sustainable electrochemical method to efficiently drive the chemical reaction ...

New world record for direct solar water-splitting efficiency

06-Jul-2018

Hydrogen will play a central role as a storage medium in sustainable energy systems. An international team of researchers has now succeeded in raising the efficiency of producing hydrogen from direct solar water-splitting to a record 19 per cent. They did so by combining a tandem solar cell of ...

Synthesis of opium alkaloids using electric current

A selective electrochemical reaction offers a solution to a long-standing synthetic challenge

02-Jul-2018

Researchers at Johannes Gutenberg University Mainz (JGU) have mastered a nearly 50-year-old challenge of electrosynthetic chemistry, namely the electrochemical synthesis of thebaine. The chemists had set themselves this difficult task within the framework of a collaboration with the University of ...

More than just spectators: Influence of ions on atomic motions investigated

03-May-2018

In batteries, fuel cells or technical coatings, central chemical processes take place on the surface of electrodes which are in contact with liquids. During these processes, atoms move over the surface, but how this exactly happens has hardly been researched. Physicists at Kiel University want to ...

Robust and inexpensive catalysts for hydrogen production

12-Apr-2018

Hydrogen gas is considered a possible future source of energy and can be produced from water using platinum catalysts and electricity. However, alternative catalysts made of cheaper and more readily available materials with equally high efficiency are barely known. Electrodes without precious ...
