In this video, I demonstrate how to make an oxygen generator using manganese dioxide (MnO2) and hydrogen peroxide (H2O2) Alaska’s record snowfall sank boats and collapsed roofs Massive fraud ...

Hydrogen peroxide is widely used but energy-intensive to produce. A new machine-learning framework helps find catalysts that can make it from water and electricity, and identifies one with about 90% ...

An international research team led by Professor Philip C.Y. Chow at The University of Hong Kong (HKU) has unveiled a new catalyst that overcomes a major challenge in producing green hydrogen at scale.

Scientists have developed a new iron-based catalyst that improves the typically low hydrogen atom economy (HAE) in the direct synthesis of olefins—small hydrocarbon molecules. It converts the water ...

Hydrogen peroxide (H2O2) packs so much chemical energy into a small space that it is powerful enough to fuel rockets. But this same ability to concentrate energy also makes hydrogen peroxide useful ...

A photoelectrochemical device uses sunlight, water, and oxygen to produce hydrogen peroxide efficiently, stably, and at scalable rates without grid electricity. (Nanowerk Spotlight) Hydrogen peroxide ...

An international team of researchers from Seoul National University, the Korea Institute of Science and Technology (KIST), and Kookmin University has developed an advanced electrochemical catalyst ...

While hydrogen peroxide (H 2 O 2) has numerous applications, its industrial production is costly and energy-intensive due to rare metal catalysts. Zinc is an abundant and historically-used element … ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

The CoPc/CB-Mag catalyst greatly enhanced the efficiency of the reaction, producing an impressive 90 % H 2 O 2, the researchers found. Notably, the catalyst uses up to seven orders of magnitude less ...

A sprinkling of magnetic nanoparticles is just enough to power up catalysts, so they can make hydrogen peroxide production more efficient. Researchers have achieved a breakthrough in improving the ...
