The weight ratio of balls to sample and the milling time have significant effects on the grain size of the Cu30Al70 alloy. The mean grain size of the CuAl2 phase in the Cu30Al70 alloy is about 12 nm after 20 h ball milling. The element Cu is homogeneously distributed in the ball-milled nanocrystalline Cu30Al70 alloy. The activity of the ball-milled Raney Cu is much higher than that of the conventional Raney Cu in hydrogenation of xylose.
