ABSTRACT
The article provides information on the development by U.S. scientists at the University of Illinois at Urbana-Champaign of a catalyst that uses hydrogen gas efficiently to remove and destroy perchlorates in contaminated groundwater. Chemistry professor and co-developer of the catalyst John Shapley stated that pechlorate has been recognised as a significant environmental contaminant in US water supplies, and its physical and chemical properties pose a serious challenge for remediation.
