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 ...

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 ...

Hydrogen is a much-debated option in terms of CO₂-neutral energy production. Electrolyzer units that split water into its constituent oxygen and storable hydrogen are supplied with electricity from ...

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, ...

Water splitting via electrocatalysis offers a sustainable route to hydrogen production, relying on efficient catalysts to drive the hydrogen evolution reaction at the cathode and the oxygen evolution ...

Water splitting through electrocatalysis converts electrical energy into storable chemical energy by driving the hydrogen evolution reaction at the cathode and the oxygen evolution reaction at the ...

When it comes to greener ways to power our cars, two main avenues are emerging: battery electric vehicles and hydrogen fuel cell electric vehicles (HCEVs) like the Toyota Mirai. Although ...

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 ...

Hydrogen is a promising clean energy source with great potential to replace greenhouse gas-emitting fossil fuels. While total water (H2O) splitting is the easiest way to obtain hydrogen (H2), this ...
