To obtain microsized nanocrystalline Zn0.9Fe0.1O‐C, a two‐step synthesis was used. First, the zinc(II) acetate dihydrate (Alfa Aesar) and iron(II) d ‐gluconate dihydrate (Aldrich) precursors were dissolved in water and the solution was spray dried with a GEA Niro Mobile Minor spray dryer to synthesize Zn0.9Fe0.1O nanoparticles. Subsequently, the powder was calcined at 450 °C for 3 h (VMK‐1400, Linn High Therm) and afterwards ground by planetary ball milling (Pulverisette 5, Fritsch) for 24 h by using yttria‐stabilized zirconia beads. The carbon coating was achieved by spray drying a dispersion of the Zn0.9Fe0.1O nanoparticles in an aqueous solution of β‐lactose, followed by calcination of the resulting powder at 500 °C for 4 h under an argon atmosphere (VMK‐135‐S, Linn High Therm). Finally, the carbon‐coated Zn0.9Fe0.1O nanoparticles (Zn0.9Fe0.1O‐C) were ground again by planetary ball milling for 2 h and granulated by spray drying.

ZIF-4 was synthesized following the method described in Ref. [37 (link)]. Zinc (II) acetate dihydrate (4.4 g, >98%, Sigma-Aldrich, St. Louis, MO, USA) was dissolved in 60 mL of propylamine (98%, DAEJUNG, Sihung, Republic of Korea). Imidazole (2.72 g, >99%, Sigma-Aldrich) was separately dissolved in 120 mL of dimethyl formamidine (DMF, 99.9%, DAEJUNG). Zinc (II) acetate solution was then added dropwise to the Imidazole solution while stirring continuously at room temperature. After 4 h of stirring, the resulting mixture was centrifugated using DMF as a solvent 3 times and dried at 80 °C for 24 h.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
