Precious metal-free nanoparticles could serve as powerful catalysts in the future, for example for hydrogen production. To optimize them, researchers must be able to analyze the properties of individual particles. A new method ...
Alkaline water electrolysis has been touted as a path to establish a hydrogen economy by converting intermittent renewable energies into clean hydrogen-based chemical energy.
When hydrogen is consumed in a fuel cell, which takes the water molecule H2O and separates it into oxygen and hydrogen, a process called electrolysis, it produces only water, electricity and heat. As a zero-carbon energy ...
A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has unveiled a new technique that gives an enhanced hydrogen production yield by five times via the deposition of highly ...
A novel catalyst synthesis method, capable of generating hydrogen from yeasts, the main microorganisms involved in alcohol and bread fermentation, has been developed. The new system can efficiently decompose water into oxygen ...
Water electrolysis is an electrochemical way for production of hydrogen, which is considered as one of the future energy carrier molecules. Therefore, looking at numerous advantages of proton exchange membrane electrolysis ...
One of the biggest challenges in making hydrogen production clean and cheap has been finding an alternative catalyst necessary for the chemical reaction that produces the gas, one that is much cheaper and abundant than the ...
Because hydrogen fuel has high energy density and does not pollute the environment, it has now shown the potential to replace fossil energy. The hydrogen evolution reaction (HER) is one of the most promising hydrogen production ...
Leiden chemists Marc Koper and Ian McCrum have discovered that the degree to which a metal binds to the oxygen atom of water is decisive for how well the chemical conversion of water to molecular hydrogen takes place. This ...
The key to promoting the hydrogen economy represented by hydrogen vehicles is to produce hydrogen for electricity generation at an affordable price. Hydrogen production methods include capturing by-product hydrogen, reforming ...
