“Tiny (nano-sized) particles of haematite (crystalline iron oxide, or rust) have been shown to split water into hydrogen and oxygen in the presence of solar energy.
“The result could bring the goal of generating cheap hydrogen from sunlight and water a step closer to reality.
“Details are published in the journal Nature Materials.
“Researchers from Switzerland, the US and Israel identified what they termed ‘champion nanoparticles’ of haematite, which are a few billionths of a metre in size.
“Bubbles of hydrogen gas appear spontaneously when the tiny grains of haematite are put into water under sunlight as part of a photoelectrochemical cell (PEC).”

(The others are nor economical, but by golly we’ll spend billions until we find something that is. Other than oil and other bad things.)
