Nanofibers dramatically increase catalytic activity for ultra-low-iridium electrolysis

Decreasing the dependence on expensive platinum-group metals like iridium is vital for the expansion of “green” hydrogen production via proton-exchange membrane (PEM) water electrolysis. Efforts to develop lower-iridium catalytic components for electrolysis have typically focused on mixing iridium into a…

Nanofiltration approach recovers aluminum from process waste

The industrial production of aluminum involves electrolysis of alumina (Al2O3) in molten cryolite, a mineral used as a solvent for the aluminum oxide raw material. Over time, the cryolite accumulates impurities, such as sodium, lithium and potassium ions, which degrade…

Metal complex surfactants allow reactions in water without organic solvents

One way to develop safer, more-sustainable chemical processes is to substitute potentially harmful chemicals with less-risky alternatives. Organic solvents, which are widely used in industrial processes, can pose health, safety and environmental risks. Researchers at Rice University (Houston, Tex.; www.rice.edu)…
