A thermoelectric conversion material is a polycrystalline material composed of a plurality of crystal grains and has a composition represented by formula (I): MgSbBiA. In the formula (I), A is at least one element selected from the group consisting of Se and Te, the value of m is greater than or equal to 0.01 and less than or equal to 0.5, the value of a is greater than or equal to 0 and less than or equal to 1.0, and the value of c is greater than or equal to 0.001 and less than or equal to 0.06. The thermoelectric conversion material has an Mg-rich region.

Thermoelectric conversion material and thermoelectric conversion device using same

The present disclosure provides a thermoelectric conversion material having a composition represented by a chemical formula of LiMgSi. In this thermoelectric conversion material, either requirement (i) in which 0≤a≤0.0001 and 0.0001≤b≤0.25-or requirement (ii) in which 0.0001≤a≤0.25 and 0≤b≤0.25-is satisfied. The thermoelectric conversion material has an LiAlSitype crystalline structure.

Thermoelectric conversion technique

The desorbing process of the present disclosure includes a step of bringing a solution containing a hydrogenated aromatic compound, at least one of [P((CH)CH)((CH)CH) (5&#x2264;m&#x2264;24, 13&#x2264;n&#x2264;24)]and [N((CH)CH)((CH)CH) (5&#x2264;m&#x2264;24, 13&#x2264;n&#x2264;24)], and an anion into contact with an anode; and desorbing hydrogen from the hydrogenated aromatic compound.

Desorbing process, hydrogen-supplying solution, and desorbing apparatus

A hydrogen desorption method includes a step of bringing a liquid containing an alicyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon side chain, a quinone, and an electrolyte into contact with a anode and a step of desorbing hydrogen from the alicyclic saturated hydrocarbon having a tertiary carbon atom bearing a saturated hydrocarbon side chain.
