【摘要】 本文采用水热法,以SnC l4.5H2O为前驱物,在180℃,填充度为68%,反应时间8h,强酸环境条件下合成了SnO2纳米金红相晶体,直径约为5~10nm,长30~100nm。加入一定量的NaOH,调节溶液pH值为强碱性(pH=11),同样条件下也合成了SnO2金红相纳米柱晶体,长200nm、直径10~20nm。提高水热反应的温度为430℃,矿化剂为3mol/L NaOH,反应时间24h,合成了亚微米金红相SnO2晶体,最大线度为300nm。更多还原

【Abstract】 The SnO₂ nanorods with rutile structure and diameters of 5-10 nm and lengths of 30-100 nm were synthesized at 180℃ for 8 hours with SnCl₄·5H₂O as precursor at high acidic solution.When the NaOH was added as mineralizer,the long nanorods crystal with diameters of 10-20nm and lengths of 200 nm were synthesized in high alkaline solution by hydrothermal method.The submicron SnO₂ crystals were synthesized at 430℃ for 24 hours with 3mol/L NaOH as mineralizer by hydrothermal method,the maximum length is 300nm.更多还原
