Hydrogen peroxide (H 2 O 2) is a clear, colorless, odorless liquid. It’s a combination of hydrogen and oxygen and is available in many strengths (indicated by the percentage of dilution with water).

By fine-tuning the surroundings of single cobalt atoms, researchers reveal how tiny design changes can steer oxygen reactions ...

The question of whether water can form hydrogen peroxide should be answered by thermodynamics (see C&EN, June 13, 2022, page 3). If a reaction is possible (spontaneous), then the change in the Gibbs ...

Limited access to clean water is a major issue for billions of people in the developing world, where water sources are often contaminated with urban, industrial and agricultural waste. Many ...
