摘      要：A novel Pd/Al 2O 3 catalyst prepared by glow discharge plasma technology is *** results of H 2-chemisorption indicate that palladium dispersion of the plasma-prepared Pd/Al 2O 3 reaches 29.7%,which is about 5 times higher than Pd/Al 2O 3 prepared by conventional ***,the particle diameter of the plasma-prepared catalyst is 3.8 nm, but the particle diameter of the conventional catalyst is 20.4 *** plasma-prepared Pd/Al 2O 3 catalyst shows a higher activity for catalytic combustion of methane than the conventional *** conversion reaches 90% at 400 ℃, but it is only near 30% for the conventional catalyst at the same temperature.
