- Abstract:
- The nano copper-cobalt bimetallic oxide (NCCO) with high catalytic activity was prepared by hydrothermal synthesis method, and it was characterized by SEM, TEM, XRD, XPS, FTIR and BET methods. By changing the preparation conditions, the synthesis of NCCO under the conditions of different dosage ratio of precursor, hydrothermal time, hydrothermal temperature, presence or absence of ultrasonic pretreatment, and presence or absence of propionaldehyde addition were explored, and the degradation effect of nitrobenzene (NB) was used as evaluation index to determine the best preparation condition of NCCO. When the precursor dosage ratio Cu ∶Co was 1 ∶1, hydrothermal time was 48 h and hydrothermal temperature was 200 ℃ with ultrasonic pretreatment and the addition of propionaldehyde, the synthesized NCCO had the best catalytic activity. In addition, NB degradation efficiency was still 100% within 45 min even after using NCCO for four consecutive times, indicating that NCCO had excellent chemical stability.
