Army Research Lab discovers aluminum nanomaterial rapidly splits water on contact

Green Car Congress

Researchers at the US Army Research Laboratory (ARL) have discovered that a nano-galvanic aluminum-based powder of their design splits water on contact, producing hydrogen and oxygen. The team demonstrated a small radio-controlled tank powered by the powder/water reaction. —Scott Grendahl.

Oregon State team demonstrates pathway to proton batteries; Grotthuss proton conduction

Green Car Congress

A team led by researchers at Oregon State University have demonstrated that diffusion may not be necessary to transport ionic charges inside a hydrated solid-state structure of a battery electrode. Theodor von Grotthuss was a German-born Lithuanian chemist who in 1806 penned the theory on charge transport in electrolytes.

New mesoporous crystalline Si exhibits increased rate of H2 production; potential use in Li-ion batteries also

Green Car Congress

The nanosized crystalline primary particles and high surface areas enable an increased rate of photocatalytic hydrogen production from water and extended working life. They then treat the material with a sodium potassium alloy. There are some processes that use sodium potassium alloy at industrial levels.
