摘要: Abstract A new Pd/Al2O3–La2O3 catalyst has been synthesized for the reduction of NO with hydrogen. This is more active than coprecipitated Pd/Al2O3 catalysts. The revealed effect improvement catalytic activity at medium temperature and increase NH3 formation high temperatures Pd supported on alumina–lanthana prepared by sol–gel method are ascribed to a lanthanum-containing phase observed X-ray powder diffraction resolution electron microscopy.
