Effect of Fe-Ni Ratio on Microstructure and DMP Degradation of Water Purification Catalysts
An iron-nickel oxide catalyst for water purification was prepared.The effect of iron-nickel ratio on the catalytic performance of dimethyl phthalate(DMP)was analyzed,and the experimental analysis was carried out.The results show that all catalysts are composed of particles with small particle size,and when the particle size is between 0.1 and 0.3 μm,they will aggregate with each other.A more uniform distribution of fine particles was formed in the ratio of Fe to Ni 1:1,which resulted in an obvious aggregation phenomenon and reduced the particle void of the Fe to Ni catalyst.When no catalyst is added to the reaction system,the degradation rate of DMP is equal to 36.46%.When the catalyst is added,the degradation rate of DMP will increase rapidly,and the iron-nickel catalyst can significantly enhance the oxidation performance of the system,so that the degradation of DMP will occur faster.This study is helpful to improve the water treatment capacity and has a good value of popularization.
