摘要：
The hydrogenolysis of ethane has been investigated over silica-supported osmium and iron. The surface areas of the metals were determined by hydrogen and carbon monoxide chemisorption. The osmium was much more active than the iron, and there was a marked difference in the dependence of reaction rates on hydrogen pressure. For osmium the rate was a strong inverse function of hydrogen pressure, while for iron the rate increased with increasing hydrogen pressure. When considered together with earlier data on the other Group VIII metals, the results strengthen the conclusion that the noble and nonnoble metals show different patterns of catalytic behavior. © 1968.
