文档介绍：济南大学毕业论文-I-摘要光催化氧化技术具有高效、节能、清洁无毒等突出优点,是一项具有广泛应用前景的新型水污染处理技术,越来越受到人们的重视。本文以硝酸镍、硫酸钛、氢氧化钠、碳酸钠为原料,采用煅烧水滑石法制备了Ni掺杂TiO2的粒子,并利用XRD的测试手段对制备的掺杂Ni的TiO2纳米粒子进行表征;以金橙Ⅱ为光催化反应模型,研究了煅烧温度、镍掺杂量、底物浓度等对TiO2光学性能及光催化活性的影响。结果表明:样品的催化活性随焙烧温度的提高而降低。样品经500℃煅烧,随Ni掺杂量增加,光催化性降低;样品的催化降解的效率随底物浓度的增加先升高当达到一个峰值时,然后降低,在10mg/L时达到最佳值;样品在镍钛比2:1、煅烧温度500℃的情况下降解效率最佳。关键词:二氧化钛;光催化降解;镍;金橙Ⅱ济南大学毕业论文-II-ABSTRACTPhotocatalyticoxidationtechnologyhasmanyprominentcharacteristics,suchashighefficiency,energysaving,cleanandnon-',ImakeparticlesthatNidopedTiO2byusingnickelnitrate,sulfate,sodiumhydroxide,,Ni-doping,thesubstrateconcentrationontheopticalpropertiesbyusingGoldorangeⅡ:℃,samples'photocatalyticreduceswiththeincreaseofNidoping,photocatalyticreduction;Theefficiencyofphotocatalyticdegradationofsamplesreachestoapeakandthendecreaseswiththesubstrateconcentrationincreasing(itreachesthebestvalueinthe10mg/L).Sample'ssolutionefficiencyisthebestwhenNi/Ti2:1,calcinedin500℃.Keywords:titaniumdioxide;photocatalyticdegradation;nickel;goldenorangeⅡ济南大学毕业论文-III-目录摘要........................................................................................................................................IABSTRACT..........................................................................................................................II1前言.....................................................................................................................................................................................................................
