研究目的
Investigating the photocatalytic performance of CoxNi1?xFe2O4/multi-walled carbon nanotube nanocomposites in the degradation of methylene blue (MB) in the presence of hydrogen peroxide (H2O2).
研究成果
The CoxNi1?xFe2O4/MWCNT composites used as novel photocatalysts have enormous potential for the photodegradation of organic pollutants, with no significant decrease in photodegradation efficiency after reuse for three cycles.
研究不足
The study focuses on the photocatalytic degradation of MB and may not cover the full spectrum of organic pollutants. The practical application in large-scale wastewater treatment needs further investigation.
1：Experimental Design and Method Selection:
The study involved the synthesis of CoxNi1?xFe2O4/MWCNTs nanocomposites via a one-step hydrothermal method and their characterization using modern analytical methods.
2：Sample Selection and Data Sources:
Methylene blue (MB) was used as the research object to investigate the catalytic effect of the catalyst.
3：List of Experimental Equipment and Materials:
MWCNTs were purchased from Yongda Chemical Reagent Development Center. Other reagents were of analytical grade.
4：Experimental Procedures and Operational Workflow:
The photocatalytic degradation of MB by the synthesized photocatalyst was evaluated in a home-made reactor using a 300 W xenon lamp as the light source.
5：Data Analysis Methods:
The concentration of MB was analyzed using a UV-vis adsorption spectrometer at 663 nm.
