Our ancestors observed that tourmaline thrown into a fire attracted and then repelled ashes. Seventeenth-century scientists began studying the effect in detail, discovering the electric charges are the result of modified crystal structures.

Currently, the most different nanoparticles are being examined in the most different structural combinations. This is also true for the field of water splitting, where catalysts are employed in electrolysis systems. The jury is still out on which materials could ultimately replace platinum in both cases, so work on the required catalyst quantity continues. (more…)
