Green H2O2 using zinc battery chemistry

Zinc-air battery repurposed to make hydrogen peroxide sustainably.

Researchers at the Indian Institute of Science (IISc) have transformed a humble zinc-air battery into a chemical reactor that produces hydrogen peroxide (H2O2) – offering a low-cost, energy-efficient alternative to a polluting industrial process.

For many eco-friendly households, hydrogen peroxide is an all-around essential item in...
