Abstract: Oxyanions such as perchlorate (ClO4−), chlorate (ClO3−), nitrate (NO3−), and bromate (BrO3−) are pervasive pollutants in water and agricultural products. Highly abundant ClO4−and NO3− on Mars have also triggered new interest in oxyanion reduction for space expeditions. However, the reduction of recalcitrant oxyanions has been challenging for decades: most chemical reduction methods require harsh conditions; microbial reactors take days or weeks to stabilize the performance; and isolated enzymes cannot utilize common electron donors. Recent heterogeneous catalysts developed by new rationales provide viable solutions. We have developed a series of rhenium (Re) and molybdenum (Mo) catalysts on palladium/carbon (Pd/C) for rapid oxyanion reduction under ambient conditions. This seminar will briefly cover our recent studies showing that (i) the “high cost of metal catalysts” is not a valid criticism and (ii) coordination chemistry has amazing powers to advance environmental technologies.
