Evidence Details
The reaction system was heated with a heating rate of 10 K min−1 and maintained at 403 K for 30 min under pressure of around 0.3 MPa.
The solution was then placed in a 100 mL Teflon-lined stainless-steel autoclave and put in a microwave reactor (XH-8000Plus, Xianghu Science and Technology Development Co. Ltd, Beijing, China).
Compared with conventional hydrothermal methods which usually require 12-36 h to produce SnSe powders, the present microwave-assisted hydrothermal method can synthesise gram-scale SnSe powders within 30 min.
It is found that a NaOH:SnCl2 molar ratio of 30 leads to the formation of phase-pure SnSe microrods, and the pellet consolidated from such rods obtains maximum ZT of 1.08 and 0.78 at 773 K along parallel and perpendicular to the pressing direction, respectively.
