Figure 1. Schematic representation of the formation of (FeCoNiCuZn)N via a low-temperature solvothermal process. (A) Schematic mechanism of (FeCoNiCuZn)N; (B) DSC results and (C) the calculated entropy values, (D) Magnified FT-IR spectrum, and (E) Raman spectrum of salts-in-PBDES and PBDES systems. PBDES: Polyethylene glycol-barbituric acid deep eutectic solvent.
