摘要
采用一种新型还原性的燃烧剂抗坏血酸与氧化性的六水合硝酸锌为原料,燃烧法合成乳白色棒状氧化锌,对燃烧剂的用量、是否煅烧和煅烧温度、是否加入助溶剂进行考察。结果表明,燃烧剂与六水合硝酸锌的物质的量之比为3:1,六水合硝酸锌与助溶剂物质的量之比为1:0.5,样品不经洗涤和煅烧,其纯度和结晶度较高。加入助溶剂样品更加蓬松,样品棒更短。样品经FTIR,XRD,UV-Vis,SEM表征,结果表明所制备的氧化锌在紫外和红外都有强吸收,粒径可达微米级,形貌为短的棒状。
synthesized were inspec With zinc nitrate as the oxidant and ascorbic acid as reducing agent and a n milky and rod zinc oxide. The burning agent dose, calcined or not, calcination tern ted. The experiment show ratio of ascorbic acid and zinc nitrate is 3 ： 1, ratio c 1 = 0.5. Product of combustion wasn＇t calcined and washed, which is high purity and good crystallinity. The samples more fluffy and shorter by adding cosolvent. The sample was characterized by FTIR, XRD, UV--Vis, SEM. Zinc oxide has strong absorption in UV--Vis and IR wave band,particles size is micron, morphology is short rod.
