Zr-MCM-41 materials were synthesized by the hydrothermal method in the presence of ZrOCl 2 and NaCl. The characterization results showed that Zr was highly dispersed in the tetrahedral environment of silica framework. In the synthesis process, the self-generated acidity by the hydrolysis of ZrOCl 2 acted as the catalyst for TEOS hydrolysis. In order to form the ordered structure of...
