Tiny bubbles on electrodes key to speeding up chemical processes

Formation of bubbles on electrodes, usually thought to be a hindrance, can be beneficial

14-Dec-2020

New Curtin University-led research has shown the formation of bubbles on electrodes, usually thought to be a hindrance, can be beneficial, with deliberately added bubbles, or oil droplets, able to accelerate processes such as the removal of pollutants such as hydrocarbons from contaminated water ...

Solar hydrogen: Let’s consider the stability of photoelectrodes

How the stability of photoelectrodes and catalysts can be compared and enhanced in the future

28-Oct-2020

As part of an international collaboration, a team at the HZB has examined the corrosion processes of high-quality BiVO4 photoelectrodes using different state-of-the-art characterisation methods. The result is the first operando stability study of high-purity BiVO4 photoanodes during the ...

New electrode materials for the oxidation of water

It’s all about good cooperation

12-Oct-2020

By splitting water electrochemically, green hydrogen can be produced, which can be used as fuel, energy storage and for chemical reactions. This way, we can decrease our dependence on fossil resources and reduce greenhouse gas emissions. However, the electrolysis of water consumes a lot of ...

Engineered electrode material moves battery research closer to 'holy grail'

An electric vehicle with such a battery could travel 600 miles on a single charge

12-Oct-2020

Electric vehicles are gaining in popularity, but their long charging time is a significant detraction for potential customers. While a typical SUV with a combustion engine could travel 300 miles with a five-minute refuel, a state-of-the-art electric vehicle takes about one hour to store enough ...

Making enzymes fit for industrial applications

Biobased process for ammonia production

27-Aug-2020

Bacterial enzymes are often powerful but also very sensitive catalysts. To call up their performance, they therefore need a special environment. Researchers at Ruhr-Universität Bochum (RUB) have developed new techniques for efficiently coupling bacterial enzymes to electrodes. Together with a ...
