The catalysts are very stable during the reaction. The presence of Bi as base center has promotion effect on the catalyst activity. The optimal Bi content is about 4% (molar fraction). With the increase of calcination temperature, the BET surface area of the catalysts is decreased and so is the activity of the catalysts. The activity of the catalysts and the Bi effect are discussed based on the reference results.展开更多
