TS-1 is a kind of molecular sieve material whose skeleton is composed of silica tetrahedron and titanium oxide tetrahedron. The introduction of tetra coordinated Ti in the skeleton gives it good catalytic performa nce. Combined with the use of H2O2 oxidant, it provides an excellent alternative for many traditional oxidation reactionprocesses with high toxicity and high pollution. In recent years, as anew generation of green catalytic oxidation technology,TS-1 has become a hot spot of attention of many researchers.
