Ni0 NCs
were synthesized following the procedure reported by Carenco et al.16 (link) In a 25 mL flask, 1 equiv of nickel acetylacetonate
[Ni(acac)2, 95%, purchased by Sigma-Aldrich] and 10 equiv
of OLAM were mixed and degassed in a standard Schlenk line under vacuum
for 2 h at 100 °C. Afterward, the atmosphere was switched to
argon and the solution was heated up to 220 °C. The reaction
time was 2 h. Then, the solution was cooled down to room temperature.
Ni0 NCs were washed three times with a mixture of hexane
(99%, purchased from Sigma-Aldrich) and ethanol (99.9%, purchased
from Carlo Erba Reagents), each rinsing followed by centrifugation
(4500 rpm, 10 min) and discarding of the supernatant. The Ni0 NCs were dispersed in hexane for further characterizations/experiments.

One-Pot Synthesis of Ni0 Nanoparticles

In a one-pot synthesis to obtain Ni0 NPs, determined amounts of nickel (II) acetylacetonate (Ni(acac)2, 1 mmol, Sigma-Aldrich, 98%), trioctylphosphine as ligand (TOP, 0.8 mmol, Sigma-Aldrich, 97%), oleylamine as solvent and reducing agent (OA, 10 mmol, Sigma-Aldrich, 70%) were directly added into a three-neck round bottom flask fitted with a condenser and magnetic stirring. The two remaining necks were used to introduce a thermocouple with a glass sheath and Ar flow, respectively. The mixture was heated at 220 °C for 2 h. Finally, the NPs were purified and isolated precipitating the suspension with acetone and re-dispersed in n-hexane.
In order to obtain nickel phosphide NPs, the same procedure was used but TOP was replaced by triphenylphosphine, acting as ligand and phosphorus source (Ph3P, 0.4 mmol, Sigma Aldrich, 99%).
The NPs were characterized by X-ray diffraction (XRD), diffuse light scattering (DLS), transmission electron microcopy (TEM), selected area electron diffraction (SAED) and Fourier transformer infrared spectroscopy (FT-IR). Atomic absorption spectroscopy (AA) was used to determine the Ni content in the suspension and in catalysts. In this work only the characterization of Ni0 NPs will be reported, because nickel phosphides characterizations were previously described [24] (link).

Synthesis of NiFe2O4 Nanoparticles

Check if the same lab product or an alternative is used in the 5 most similar protocols
For each synthesis of NiFe2O4 nanoparticles, 128.5 mg (0.5 mmol) Ni(acac)2 (SigmaAldrich, for synthesis) and 353.2 mg (1 mmol) Fe(acac)3 (Acros Organics, +99 %) were dissolved in 15 mL of rac‐1‐phenylethanol (SigmaAldrich, 98 %) using ultrasonication. The obtained solution was transferred into a 30 mL borosilicate microwave glass vessel. The solution was then heated as fast as possible to a maximum temperature of 200–275 °C (standard 225 °C) for typically 30 min using microwave irradiation (Anton Paar Monowave 400 equipped with MAS24 autosampler) under constant stirring (600 rpm). Next, the reaction mixture was cooled down to 55 °C using compressed air. To study the influence of the reaction time, the reaction was performed additionally for 5–25 min (5 min steps) at 240 °C. Obtained nanoparticles were precipitated with n‐pentane and washed for three times with water/acetone mixtures (3 : 1, 12 : 1, 12 : 1) and diethyl ether. The resulting powder was dried at 80 °C overnight. To remove remaining organic residues and to adjust the crystallite size, the as‐synthesized samples were further calcined in a Nabertherm muffle furnace under air atmosphere at 300/400/500 °C (heating rate 5 °C/min, holding time 5 h).[34, 37]

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.
