Abstract
Abstract The CuO–CeO2 composite oxides supported on Y-zeolite were prepared by means of wet-impregnation method. The derived catalysts exhibited excellent activities and high stabilities for gas-phase HCl catalytic oxidation to Cl2. 90% conversion of HCl can be accomplished at a reaction temperature as low as 390 °C. Comparing with the results reported in literature, the CuO(12)–CeO2(13)/Y catalyst developed in the current study showed exceptionally high space time yield for Cl2 (62.7 mmol gcat−1 h−1 at 410 °C). A correlation between the characterization results and the activities of CuO–CeO2/Y suggested that higher content of well dispersed CuO species and intensive CuO–CeO2 association (the formed CuxCe1−xO2−y and surface oxygen spillover) are critical to determine high activity.
