Proton exchange membrane water electrolysis (PEMWE) is promising due to its high energy efficiency and hydrogen purity. However, as the practical application of the PEMWEs usually runs at high current densities (≥1–2 A m-2), ...
Seawater, which comprises more than 95% of the Earth's water, could become a key resource in the sustainable production of clean hydrogen fuel with use of water-splitting catalysts developed by a KAUST-led team.
Coupling renewable energy to produce hydrogen by the electrolysis of water is an effective way to develop new energy utilization and solve the energy crisis. It is important to fully understand the cathodic hydrogen evolution ...
Creating a hydrogen economy is no small task, but Rice University engineers have discovered a method that could make oxygen evolution catalysis in acids, one of the most challenging topics in water electrolysis for producing ...
The Haber-Bosch process, which is commonly used to synthesize ammonia (NH3)—the foundation for synthetic nitrogen fertilizers—by combining hydrogen (H2) and nitrogen (N2) over catalysts at high pressures and temperatures, ...
Green hydrogen is an energy carrier with a future. It is obtained by electrolytically splitting water with energy from wind or sun and stores this energy in chemical form. To make the splitting of water molecules easier (and ...
The accumulation of plastic waste in the oceans, soil, and even in our bodies is one of the major pollution issues of modern times, with over 5 billion tons disposed of so far. Despite major efforts to recycle plastic products, ...
Our excessive consumption of fossil fuels is responsible for some of the major societal challenges we are facing, from climate change to pollution. Hydrogen is considered a green alternative to fossil fuels, and alkaline ...
As the need to mitigate climate change accelerates, scientists are trying to find new ways to reduce carbon dioxide emissions. One process, called electrochemical reduction or electrolysis, uses electricity and a catalyst ...
Controlling the spin of electrons opens up future scenarios for applications in spin-based electronics (spintronics), for example in data processing. It also presents new opportunities for controlling the selectivity and ...
