Porous silica is referred to as a chemically and thermally stable material with uniform pore size. Metal cerium from cerium sulfate metal salt is impregnated into silica, with the addition of sulfuric acid to increase its solubility. In this study, Ce(SO4)2-SiO2 with KHPhthalate template was used as a catalyst synthesized by calcination, impregnation and hydrothermal methods, and its applicatio…
