Sunlight gives biodiesel byproduct a second life as hydrogen

Australian researchers and international collaborators have demonstrated a solar-driven approach to convert glycerol, a low-value byproduct of biodiesel production, into hydrogen and higher-value chemicals. Using advanced techniques at the Australian Synchrotron, the team revealed how the catalyst changed while it was actively working. This discovery paves the way for more efficient waste valorization and sustainable energy production.

Chemists uncover the true active surface of nickel catalysts

Researchers at Ulm University have revealed that the true active surface of nickel catalysts used in alkaline water electrolysis is nickel dioxide (NiO₂), refuting the long-held assumption that it was nickel oxyhydroxide (NiOOH). This discovery marks a significant step forward in understanding hydrogen production technologies, providing vital insights that could optimize cost-effective, climate-neutral energy solutions.

Light-Driven Method Harnesses Reactive Hydrogen Atoms for Synthesis

Scientists have developed a groundbreaking light-driven method to stabilize and utilize single hydrogen atoms (H•) for chemical synthesis. This breakthrough overcomes a century-old challenge in chemistry, as these atoms are typically too reactive to be harnessed effectively. By utilizing precise light activation, researchers can now control these elusive particles. This innovation opens new pathways for creating complex chemical compounds with greater efficiency and precision than previously possible.
