摘要
Abstract
Two different crystal forms of nickel-manganese oxides,namely NiMn2O4 and NiMnO3,were successively loaded on cordierite honeycomb ceramics by sol-gel method,thereby fabricating a composite photocatalytic material with NiMn2O4 as the bottom layer and NiMnO3 as the surface layer.Using testing methods such as XRD,XPS,SEM,the structural morphology and photoelectrochemical properties of the samples were analyzed.Evaluated by visible-light degradation reaction of methylene blue dye,the photocatalytic performance of the material was assessed,and the photocatalytic mechanism of NiMn2O4/NiMnO3 composite photocatalytic material was discussed.Results indicate that the controllable preparation of two crystal forms of nickel-manganese oxides,NiMn2O4 and NiMnO3,was achieved by adjusting the ratio of nickel and manganese nitrate precursors and the pH value of the reaction system.By constructing a heterojunction using the two different crystal forms of nickel-manganese oxides effectively facilitates the transfer of interfacial charges,suppresses the recombination of photo-generated carriers,and enhances the photocatalytic quantum efficiency.In addition,this method realizes the firm loading of the photocatalytic materials on the surface of honeycomb ceramics,which is beneficial for the recovery and reuse of the photocatalytic material.After six consecutive cycles,the attenuation rate of its photocatalytic performance was merely 2.15％.关键词
