exfoliated molybdenum disulfide (mos2) electrode for a third technique for biohydrogen production from organic matter, including wastewater, is known as a microbial electrolysis cell (mec) and was first described in 2005 . this process occurs in a device similar to that of the microbial fuel cell (mfc) . mec is an electrolytic process which requires extra potential, while mfc is a galvanic process that produces electricity.

metal production by electrolysis in molten saltselectrolysis, molten salts, metal production . 1. introduction . many important metals are being produced by electrolysis, in aqueous electrolytes (cu, ni, co and others) and molten salts (al, na and other reactive metals). also industrial electrorefining processes have been established in aqueous electrolytes (cu) and molten salts (al).

electrolysis of water electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current. this technique can be used to make hydrogen gas , a main component of hydrogen fuel , and breathable oxygen gas, or can mix the two into oxyhydrogen also usable as fuel, though more volatile and dangerous.
