Rhizomes of Cimicifuga heracleifolia Komar. with rootlets removed and rhizomes of Cimicifuga heracleifolia Komar. with rootlets scorched were dried and pulverized, then passed through a No. 2 sieve. 400.00g of the powder of rhizomes with rootlets removed and 400.00g of the powder of rhizomes with rootlets scorched were extracted by refluxing three times with 15 times the volume of 70% ethanol for 2 hours each time. The extracts were combined, concentrated, and lyophilized to obtain the ethanol extract of rhizomes with rootlets removed and the ethanol extract of rhizomes with rootlets scorched.

A ternary composite was synthesized via an ex-situ method. 0.8 g of graphene oxide (GO) was added to 100 ml of distilled water and sonicated for 1 hour at 30 degrees Celsius. Separately, 1.1 g of zinc-based metal-organic framework (Zn MOF) was added to 100 ml of distilled water and sonicated at 30 degrees Celsius for 1 hour. In a separate beaker, 1.1 g of Sr2NiMoO6 double perovskite was added to 50 ml of distilled water and sonicated at 30 degrees Celsius for 30 minutes. After these steps, the double perovskite was mixed into the GO and Zn MOF suspension and stirred on a hotplate at 40 degrees Celsius for 1 hour, followed by sonication for 30 minutes. The mixture was then transferred to an autoclave and heated in an oven at 180 degrees Celsius for 12 hours. Finally, the product was centrifuged three times with distilled water, dried in an oven, and calcined at 250 degrees Celsius for 1 hour.

Initially, 7 g of zinc nitrate hexahydrate and 2.5 g of benzene-1,3-dicarboxylic acid (the organic linker) were separately placed in two beakers. A solvent mixture of 30 mL of deionized water and 10 mL of ethanol was gradually added to each beaker to dissolve the chemicals. The solutions were stirred at 50 °C to ensure complete dissolution of the zinc nitrate. Subsequently, the organic linker solution was combined with the zinc nitrate solution, and the resulting mixture was stirred again at 50 °C for 30 minutes. This mixing step facilitated the interaction between the zinc ions and the organic linkers, initiating framework formation. The solution was then transferred to an oven and heated at 150 °C for 8 hours, resulting in the formation of yellow solid particles. The supernatant was discarded, and the zinc-MOF particles were washed several times.
