Hydrogen Generation From Water Using Mg Nanopowder Produced by Arc Plasma Method

open access: yesScience and Technology of Advanced Materials, 2012
We report that hydrogen gas can be easily produced from water at room temperature using a Mg nanopowder (30–1000 nm particles, average diameter 265 nm). The Mg nanopowder was produced by dc arc melting of a Mg ingot in a chamber with mixed-gas atmosphere
