Compared with the unloaded cerous sulfate , the multiple - walled carbon nanotube loaded cerous sulfate possessed some obvious advantages of higher catalytic activity , less use level and higher yield of n-butyl propionate .

与未担载硫酸铈相比，碳纳米管担载硫酸铈具有催化活性高、催化剂用量少、重复使用率好和丙酸丁酯得率高等显著优点。

The results shown the materials doped with cerous nitrate and rare earth chlorides had better comprehensive properties than the materials with ceric sulfate .
