					<description><![CDATA[A new study shows that doping just 1 weight percent of lanthanum into cobalt oxide catalysts boosts low-temperature carbon monoxide removal from hydrogen streams with perfect selectivity and improved resistance to moisture, though carbon dioxide still causes a roughly 30 percent activity loss over time.]]></description>
