In a laboratory demonstration of the old adage “one man’s trash is another man’s treasure,” researchers in Turkey have shown that red mud, a hazardous by-product of aluminum processing, can be converted simply and inexpensively to a catalyst that liberates hydrogen from ammonia (Sci. Rep. 2016, DOI: 10.1038/srep32279). The finding might lead to a more practical way to safely store . . .
