摘要：
The influence of calcination temperature on the performance of tin-antimony catalysts has been investigated. It is shown that the specific activity for the formation of butadiene from 1-butene may be directly related to the concentration of antimony cations at the surface. It is proposed that isolated antimony cations surrounded entirely by tin ions in nearest neighbor sites constitute an active site for the formation of butadiene. © 1979.
