The Au NPs used in this study were synthesized by refluxing a HAuCl4 solution containing Au together with the reducing agent sodium citrate.
The samples prepared by refluxing the solution in acidic (pH 2), neutral (pH 7), and alkaline mediums (pH 11) have been designated as E1, E2, and E3, respectively, in the following text.
The samples prepared by refluxing the solution in acidic, neutral, and alkaline mediums (pH 2, 7, and 11) in argon have been designated as Ar1, Ar2, and Ar3, respectively.
As a comparison, we also synthesized Se/Te NWs by a similar chemical solution process using long Te nanorods as crystalline seeds; that is, the Te nanorods are prepared by refluxing the resulting solution containing Te nanocrystalline for 6 days at room temperature.
Pure NiAl-layered double hydroxides (LDHs) and graphene oxide (GO)/NiAl-LDHs composites are both fabricated by refluxing solution with the assistance of microwave irradiation within 2 hours.
Thiol groups were then grafted on the γ-Al2O3 fibers by refluxing the toluene solution of 3-mercaptopropyltrimethoxysilane (MPTMS).
While refluxing an aqueous solution of Gd3+ salt, urea serves as a precipitating agent for the Gd3+ ions by shifting the pH value into basic conditions due to self-decomposition at elevated temperature.
Finally, the recovery of the catalytic activity by regeneration of the spent catalyst by refluxing in nitric acid solution was demonstrated.
When the solution began to reflux, an aqueous solution of trisodium citrate (228 mg in 20 mL water) was quickly added and the resulting solution was continuously refluxed.
Complexes C1 C10 have been synthesized by refluxing [Ir(C^N 2Cl]2 in dichloromethane acetonitrile solution at 60 °C with ligand 1 9, where systematic substitution of various functional groups have been done.
