Green hydrogen (or H 2) produced from renewable energy resources is the fuel of a decarbonized future. Electrolysis, or splitting of water into oxygen and hydrogen with the help of an electrochemical ...

Electrocatalysts play a key role in enabling hydrogen generation through water splitting. Among the latest materials under investigation, two-dimensional (2D) materials known as MXenes have shown ...

As the global pursuit for sustainable energy solutions intensifies, water splitting remains a promising avenue for producing clean hydrogen fuels. But the process of splitting water into hydrogen and ...

A new study has revealed key factors limiting the efficiency of photoelectrochemical water splitting using a titanium dioxide photoanode for clean hydrogen production. Researchers combined ...

Thermochemical splitting, where a catalyst splits water into hydrogen and oxygen, is emerging as a promising method for hydrogen production. However, current catalysts split water at 700–1000 o C and ...

To explore the reason why water splitting suffers from inefficiency, the researchers applied a sophisticated new light-based technique called phase-resolved second harmonic generation. Shown here, the ...

For the first time, Northwestern University scientists have watched water molecules in real-time as they prepared to give up electrons to form oxygen. In the crucial moment before producing oxygen, ...

Hydrogen is an incredibly powerful fuel, and the ingredients are everywhere—in plain old water. Researchers would love to be able to use it widely as a clean and sustainable energy source. One catch, ...

Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have ...
