Easy aluminum nanoparticles for rapid, efficient hydrogen generation from water

“We don’t need any energy input, and it bubbles hydrogen like crazy. I’ve never seen anything like it”

22-Feb-2022 - Aluminum is a highly reactive metal that can strip oxygen from water molecules to generate hydrogen gas. Its widespread use in products that get wet poses no danger because aluminum instantly reacts with air to acquire a coating of aluminum oxide, which blocks further reactions. For years, ...
