, 2007 采用固相合成法制备出系列Fe掺杂的Bi2Sr2Co2Oy样品，并对样品进行XRD分析，电阻率(ρ)、热电势(S)和顺磁共振研究。结果表明：Fe掺杂浓度x ≤0.3时样品基本为单相。Fe掺杂使体系的电阻率略微增大，热电势显著升高，这可能与Fe掺杂降低了空穴载流子浓度有关。Fe掺杂浓度x=0.05样品获得最大的功率因子(power factor，S2/ρ)。顺磁共振结果显示，不掺Fe的样品有着较强的顺磁共振(ESR)信号，随着Fe含量的增加，ESR信号向低频方向移动，并逐渐宽化减弱直至消失 ...

, 2006 采用溶胶-凝胶法通过分步控制工艺制备了镍离子不同掺杂方式的TiO2薄膜.通过甲基橙的光催化降解动力学来表征其光催化活性.结果表明：镍离子非均匀掺杂在掺杂量0.5%时可以明显增强TiO2的光催化活性,而均匀掺杂提高TiO2的光催化活性较小.光电化学表征结果显示：镍离子非均匀掺杂TiO2薄膜的瞬时光电流信号较强,说明其光生载流子易于生成且分离效果较好;循环伏安曲线表明,光照时Ni非均匀掺杂的TiO2薄膜改变了体系的氧化还原电位,说明了薄膜内建电场的建立.基于半导体的P ...

, 2012 河北省唐山迁西地区的软锰矿成分复杂,含有较高的镁含量,必须将镁去除才可进行后续利用。该实验采用在软锰矿浸锰流程之前,对于其中的镁进行预脱除。实验结果表明:在最优条件下,该方法的脱镁率可以达到78%以上。脱镁处理后的软锰矿浸锰实验结果表明:镁脱除后的软锰矿的Mn浸出率未受到影响,Mn/Mg大幅提高,而且浸出过程中的酸耗降为脱镁处理后的1/2 ...
