Preparation of ZnCe-LDO heterostructured catalyst and its photocatalytic degradation performance
In response to the problem of tetracycline antibiotics accumulating in the environment due to their stable properties and difficulty in complete degradation,which have adverse effects on both the environment and human health.Photocatalytic technology,as an effective new technology for degrading pollution,has the advantages of high efficiency,low cost,environmental protection,and no secondary pollution,which has attracted the attention of a large number of researchers.Based on the prepared ZnCe-LDH and ZnCe-LDO heterostructure catalysts,photocatalytic degradation experiments of tetracycline hydrochloride are carried out.The absorbance test results are applicable to the first-order reaction kinetics equation.Through linear fitting,it is verified that the photocatalytic performance of the heterostructure catalyst calcined at 500℃is superior to that of Zn-Ce hydrotalcite and other products calcined at different temperatures,and the degradation performance is superior.
