What is In-Situ Growth of Embryonic TS-1 on Amorphous Silica via Steam-Assisted Crystallization: Correlation of Structural Properties and Catalytic Performance of Embryonic, Crystalline, and Amorphous Titanosilicate Catalysts about?

In-situ growth of supported embryonic TS-1 zeolite ( 97%) in the productive utilization of the oxidant in DBT oxidation. The activity of the amorphous titanosilicate (TOF: 21.2-210 h -1 at 30-80 °C), the solid precursor of the SAC process, was higher than that of the embryonic and the crystalline TS-1. The analysis of the structural properties-catalytic performance of these catalysts showed an improved accessibility to defective Ti active sites "Ti(OH)(OSi) 3 " with higher catalytic activity. The results of this study should be encouraging to unearth many other active amorphous catalysts with the potential of industrial application.
