Description
Summary:Thermoelectricity has been recognized as an environmentally friendly energy conversion technology due to its ability to directly achieve conversion between heat and electricity for a long time. β ‐Zn 4 Sb 3 has attracted considerable interest as promising thermoelectric material in the moderate temperature range (500 K–900 K), which is the temperature range of most industrial waste heat sources. In this paper, first we present the structure of β ‐Zn 4 Sb 3 and the traditional doping strategy used to enhance its performance. Next, we review the details of some new methods utilized for improving the thermoelectric properties of β ‐Zn 4 Sb 3 and its thermal stability as well as reliability. Finally, the review finishes with highlighting some promising strategies for future research directions in the material.
