Metal salt precursors (PdCl2, Pd(ac)2, Sn(ac)2, and SnCl2) were purchased from Acros, Fluka, Strem, and Sigma Aldrich, respectively. 1 M KBEt3H in THF was purchased from Sigma Aldrich. Anhydrous THF was purchased from Sigma Aldrich and stored over molecular sieve (3 Å). Trioctylmethylammonium bromide was purchased from Sigma Aldrich and dried using the following procedure: (1) RT for 16–32 h, 10−3 mbar and (2) 70 °C for 0.5–1 h, 10−3 mbar. Methyltrioctylammonium bis(trifluoromethylsulfonyl)imide ([OMA][NTf2]) was obtained from IoLiTec (H2O content <100 ppm; halide content <100 ppm) and dried in vacuum prior to use (10−3 mbar, 70 °C, 3 h; 10−4 mbar, RT, 16 h). All manipulations for NP synthesis and catalytic testing were carried out using common Schlenk techniques and the anoxic glove box under argon atmosphere and anhydrous solvents.

We used second-generation Boltorn H hyperbranched polyester polyol with 16 terminal hydroxyl groups (Mr = 1750 g mol−1, Perstorp Speciality Chemicals AB, Sweden), maleic anhydride (99%, Acros Organics, Waltham, MA, USA), SnCl2 (98%, Acros Organics, Waltham, MA, USA), Gd(NO3)3∙5H2O (99.9%, Acros Organics GmbH, Waltham, MA, USA), and Dy(NO3)3∙5H2O (99.9%, Alfa Aesar GmbH, Haverhill, MA, USA). The organic solvents used were 1.4-dioxane, benzene, acetone, ethanol, methanol, and distilled water.

SnFe2O4 NCs were prepared with a single-step carrier solvent assisted interfacial chemical reaction method11 (link). In brief, a precursor aqueous solution was first formulated by dissolving a suitable amount (0.0469 M) of SnCl2 (98%, obtained from Alfa Aesar) in 62.5 mL ethanol (Sigma-Aldrich, 99%), followed by adding a stoichiometric amount of Fe(NO3)3˙9H2O (98%, J.T. Baker). An amount of 62.5 mL of the precursor solution was supplemented into chloroform (99%, Sigma) in a same volume, to produce the organic phase of the liquid-liquid interfacial reaction enviroment. The aqueous phase solution was made by dissolving a desired amount (1 M) of NaOH (Showa, >95%) in 125 mL of distilled (DI) water, and was next dripped slowly to the organic phase to generate the liquid-liquid interfacial reaction system with the aqueous domain floating on top of the organic phase. The interfacial reaction performed at room temperature for 60 min under magnetic stirring in the organic phase. The product SnFe2O4 NCs were alternately washed with distilled (DI) water and ethanol several times for removing impurities and were then collected with a centrifuge (8000 rpm, RT, 10 min). They were further dried in an oven (80 °C) overnight for later use.

To prepare Sn NPs, a solution of NaBH 4 (96 mmol, 98%, ACBR) in anhydrous 1-methyl-2-pyrrolidone (NMP, 85 mL, 99.5%, Fisher BioReagents) was heated to 60 °C under flowing N 2 . Then, a solution of SnCl 2 (1 mmol, ≥99%, Alfa Aesar) in anhydrous NMP (3 mL) was injected and the reaction mixture was immediately cooled to room temperature using a water-ice bath. To prepare Co NPs, a NaBH 4 solution in anhydrous NMP (32 mmol in 15 mL) was heated to 150 °C under flowing N 2 , followed by the injection of CoCl 2 (8 mmol, ≥98%, Sigma-Aldrich) and immediate cooling to room temperature using a water-ice bath. The obtained Co NPs and Sn NPs were purified by washing once with dimethyl sulfoxide and then two times with water after separation from the supernatant by centrifugation. Finally, the reaction product was dried under vacuum at room temperature.
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.
