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 ...

Photocatalytic water splitting harnesses solar energy in the presence of a semiconductor catalyst to decompose water into hydrogen and oxygen. Two-dimensional materials, characterised by atomic ...

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, ...

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 ...

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 ...

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 ...

Scientists are urgently searching for clean fuel sources—such as hydrogen—to aid in the move toward carbon neutrality. A breakthrough for improving the efficiency of the photocatalytic reaction that ...
