An efficient Cu-K-La/γ-Al2O3 catalyst for catalytic oxidation of hydrogen chloride to chlorine

- Cu-K-La/γ-Al2O3 catalyst was prepared by the incipient wetness impregnation method.
- The synergistic promoters of KCl and LaCl3 greatly increase the catalytic activity.
- Cu-K-La/γ-Al2O3 catalyst shows good catalytic performance and stability.
