摘要：
Uniform ruthenium metal nanoparticles with an average diameter of 5 nm have been prepared and supported on gamma -Al2O3 up to 6.3 wt%. The Ru/Al2O3 catalyst prepared by this method had unusually high activity for ammonia synthesis. The rate of ammonia formation was at least 12 times higher than the rate of non-promoted Ru/Al2O3 catalysts prepared by conventional impregnation methods.
