摘 要: Nanosized rare earth solid superacid SO42/TiO2-Nd2O3 was prepared and was used as a catalyst for cyclohexand dehydration to form cyclohexene.The influence of various preparation parameters such as the concentration of Nd3+,the concentration of H2SO4 and the calcination temperature on the catalytic activity was studied.It indicates that SO42-/TiO2-Nd2O3 has fairly high catalytic activity on the dehydration of cyclohexand and the yield of cyclohexene can reach 79.73%.The SO42-/TiO2-Nd2O3 catalytic mechanism for cyclohexand dehydration and the Nd3+ effect on the catalytic activity was also disccused.
