Towards sustainable electrochemistry: green synthesis and sintering aid modulations in the development of BaZrYMO (M = Mn, Co, and Fe) IT-SOFC electrolytes.

In this study, BaZrYMO perovskite electrolytes with sintering aids (M = Mn, Co, and Fe) were synthesized by a sustainable approach using spinach powder as a chelating agent and then compared with chemically synthesized BaZrYMO (M = Mn, Co, and Fe) electrolytes for intermediate temperature SOFCs. This is the first example of such a sustainable synthesis of perovskite materials with sintering aids. Structural analysis revealed the presence of a cubic perovskite structure in BaZrYMO (M = Mn, Co, and Fe) samples synthesized by both green and conventional chemical methods.
