High catalytic activity of Mo-Zn-Al-O catalyst for dye degradation: Effect of pH in the impregnation process

- The effect of impregnation pH value on the degradation of cationic orchid X-BL by Mo-Zn-Al-O catalyst under room conditions was studied.
- The optimum impregnation pH value ranges from 7 to 8.
- Structural characteristics and morphological information of these catalysts were discussed.
