Isomorphous substitution of Zr in the framework of aluminosilicate HY occurred during the preparation of electrogenerated zirconia supported HY (EGZrO 2/HY) catalyst via a simple electrochemical method. Dealumination accompanied by an ion exchange with Zr 4+ formed SiOZr bond, which controlled the f...
