简介：NanocrystallineNi1?有0的xZnxFe2O4铁酸盐?x?1被一个水花一起沉淀方法成功地准备。微观结构被使用XRD和TEM调查。磁性与颤动被测量在房间温度的样品磁强计(VSM)。结果证明谷物nanocrystalline缩放Ni1?在600点锻烧的xZnxFe2O4铁酸盐?祥獥Δ

简介：AseriesofCd1-xZnxS/K2La2Ti3O10compositesweresynthesizedviaasimpleco-precipitationmethod.ThepreparedsampleswerecharacterizedbyX-raydiffraction（XRD）,scanningelectronmicroscopy（SEM）,X-rayenergydispersivespectroscopy（EDX）,ultraviolet-visiblediffusereflection（UV-Vis）,X-rayphotoelectronspectroscopy（XPS）andphotoluminescence（PL）measurements.ThecompositestructuresconsistedofCd1-xZnxSnanoparticlesevenlydistributedonthesurfaceofK2La2Ti3O10.TheabsorptionedgeofK2La2Ti3O10shiftedtothevisiblelightregionuponintroductionoftheCd1-xZnxSnanoparticles.Thephotocatalyticactivitiesofthecatalystswereevaluatedbyhydrogenproductionundervisiblelightirradiation.ThepreparedCd0.8Zn0.2S（30wt%）/K2La2Ti3O10exhibitedhigherphotocatalyticactivity,evolving6.92mmol/gH2undervisiblelightirradiationfor3h.ThepromotedphotocatalyticactivityofthecompositeswasattributedtothesynergisticeffectbetweenCd1-xZnxSandK2La2Ti3O10,whichresultedinenhancedseparationofphotogeneratedelectronsandholes.
