摘要 介绍了NaxCo2O4氧化物热电材料的基本结构和热电性能,论述了NaxCo2O4热电材料的研究进展,并对NaxCo2O4材料的Na位掺杂(掺入K,Sr,Y,Nd,Sm,Yb,Ca,Ag)和Co位掺杂(掺入Ti,Rh,Pd,Pb,Mn,Ru)进行了评述·不同元素对Na位和Co位的掺杂效果的影响是不同的,但可以看出NaxCo2O4热电材料的掺杂研究有着非常好的研究价值和应用前景· Introduces briefly the basic structure and properties of the Na_xCo_2O_4 oxides as thermoelectric materials and reviews the ways to improve their thermoelectric properties. Discusses both the effects of Na-site doping (with K,Sr,Y,Nd,Sm,Yb,Ca and Ag as substituents)and Co-site doping (with Ti,Rh,Mn and Ru as substituents) of the materials Na_xCo_2O_4. It is found that the effect of different elements on Na-site doping is different from that on Co-site doping. However, the investigation on the doping of Na_xCo_2O_4 is worthwhile with prospective applications.
