microscopy (SEM, Hitachi-SU8000, Taipei, Taiwan) and scanning transmission
electron microscopy (JEOL JEM-2100F Cs STEM, Taipei, Taiwan) with
an acceleration voltage of 200 kV. A Horiba Scientific (Taipei, Taiwan)

was used to measure Raman spectra. The laser beam was focused on the
sample surface in an area of about 10 μm in size. Raman spectra
reveal the nanostructures of the sample. FTIR measurements were conducted
on a Thermo/Nicloet, FTIR spectrometer (Thermo Fisher Scientific,
Taipei, Taiwan) at room temperature under N2 flow with
a resolution of 4 cm–1 and spectral range 650–4000
cm–1. Attenuated total reflectance analysis was

Synthesis of Gold Nanoparticles

Gold nanoparticles were synthesized through reduction. Hydrogen tetrachloroaurate (HAuCl4, Sigma‐Aldrich, St Louis, MO) was used as a gold precursor, and trisodium citrate was used as a reducing agent. Briefly, 0.5 mM hydrogen tetrachloroaurate dissolved in 300 mL distilled water followed by boiling for 10 min. Note that 30 mL of 38.8 mM trisodium citrate ((HOC(COONa)(CH2COONa)2, Sigma‐Aldrich, St Louis, MO) solution was added into the gold precursor solution to allow the color change from light yellow to colorless. Then, the solution started darkening, and the reaction was terminated when the color of solution became red. This gold particles solution was ready to use after cool down and storage in 4°C. Gold particles’ size was determined by the Zeta‐sizer (Malvern Zeta‐sizer Nano ZS90) and transmission electron microscopy (TEM, JEOL JEM‐2100F CS STEM). Figure S3 presents particle size analysis. The particle size measured by the Zeta‐sizer averaged 18.71 nm, which consistent to that observed in TEM. In addition, the numerical value of PDI was 0.41 resulting in uniform particle size distribution.

The microstructure, morphology and crystallinity of the as-prepared CuO and CuO/NiO nanowires were analyzed by transmission electron microscopy (TEM, JEM-2100F CS STEM, JEOL, Japan), scanning electron microscopy (SEM, SU8000, JEOL, Tokyo, Japan), and X-ray diffraction (XRD), respectively. The CuO/NiO nanowires were assembled into coin cells as the anode for testing LIB performance. The assembling sequence from bottom to top is as follows: bottom stainless steel case, Li metal cathode, separator, CuO/NiO nanowires, spring, and top stainless steel case; the electrolyte is ethylene carbonate (EC)/diethyl carbonate (DEC) with 1 M LiPF6. The cycle tests of the anode materials were performed between 0.1–3 V under a constant current of 0.1 C (70 mA g−1) at room temperature. For comparison, evolution of the morphology and microstructure of the CuO/NiO nanowires upon cycling were studied by TEM, where a constant current of 1 µA was employed for the formation process in the 1st cycle by Keithley 2400.

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.
