Synthesis, characterization and photocatalytic activity of engelhard titanosilicates (Ets-4)
Engelhard Titanosilicate-4 (ETS-4) is a microporous zeo-type. material which contains framework of semiconductive monoatoiruc -O-Ti^-O- chains that useful for photocatalysis. In this study, ETS- 4 materials were synthesized by the hydrothermal method using two different initial molar compositions. T...
