The invention discloses a preparation method of a porous
TiN electrode material of an AMTEC, and is used for solving the technical problem that an existing preparation method of the porous
TiN electrode material is poor in practicability. According to the technical scheme, the method comprises the steps: dissolving butyl
titanate in absolute ethyl
alcohol, and adding the obtained
mixed solution dropwise into
distilled water which is stirred violently to generate precipitates; performing the washing,
drying, calcining and high-temperature nitridation of the precipitates to obtain a nano
TiN material; performing the surface treatment of a BASE tube, assembling TiN
active electrode materials on a
cathode and an
anode of the BASE tube after surface treatment by adopting a silk-screen printingmethod, and finally heating the BASE tube to obtain the
porous electrode of the AMTEC. According to the invention, the method does not employ
hydrogen in the preparation process, is simple, is low inpreparation cost, achieves the safe preparation of large-batch
coating materials, guarantees the activity and the stability of the electrodes, and is good in practicality.
