摘要
The system of the catalyst S2O82-/ZrO2-SiO2-Sm2O3 were studied by IR,and the effect on the catalyst characters by different Si/Zr atom ratio,immersing solution and rare earth were studied.The result showed that the catalyst has the best activity when the Si/Zr atom ratio is 15%,3.0% Sm2O3 and immersing solution was S2O82- instead of SO42-.The deduction of S2O82- maybe formed a bridge structure with Zr not with Si were explained well here.
The system of the catalyst S2O8^2-/ZrO2-SiO2-Sm2O3 were studied by IR, and the effect on the catalyst characters by different Si/Zr atom ratio, immersing solution and rare earth were studied. The result showed that the catalyst has the best activity when the Si/Zr atom ratio is 15% , 3.0% Sm2O3 and immersing solution was S2O8^2- instead of SO4^2-. The deduction of S2O8^2- maybe formed a bridge structure with Zr not with Si were explained well here.
