Synthesis and Characterization of Zn-Doped Cu2O Nanocrystals

The Zn-decorated Cu₂O NCs were prepared by a wet-chemical ligand-free method (see ESI†) and were spray-coated on a carbon-based GDE (Sigracet 28BC). The Cu : Zn ratio was later quantified by comparing the absorption edge steps in X-ray absorption data at the Cu K-edge and the Zn K-edge, acquired in transmission mode. For the three bimetallic samples that were investigated, the obtained Zn percentages were 4%, 7% and 15%. The ex situ characterization of the NCs was done using a scanning transmission electron microscope (STEM, FEI Talos F200X microscope, Thermo Fisher Scientific) and an energy dispersive spectroscopy (EDX, SuperX 4 SDD EDX detector) featuring an XFEG field emission gun (200 kV) to determine the morphology and elemental distribution of the samples. The detectors in use were bright-field (BF), dark field (DF) and high angle annular dark-field (HAADF) detectors.

The morphologies of Cr₂S₃ nanoflakes were examined using Atomic Force Microscopy (AFM, Park system XE7, Suwon, South Korea). Transmission electron microscope (TEM) characterization was carried out on a FEI Talos f200x microscope (Thermo Fisher, San Francisco, CA, USA) operated at 200 KV. The X-ray photoelectron spectroscopy (XPS) spectra were recorded employing Al Kα radiation from a XSAM800 spectrometer (Kratos, Manchester, UK). The binding energy of samples was calibrated by C 1s peak. XRD patterns at variable temperatures were examined using Rigaku SmartLab (Tokyo, Japan). The magnetic properties were studied by a physical properties measurement system (PPMS, Quantum Design, San Diego, CA, USA) with a vibrating sample magnetometer option (Ever Cool II).

TiO2 Nanoparticle Characterization by TEM

Check if the same lab product or an alternative is used in the 5 most similar protocols

Powder TiO₂ samples were dispersed in distilled water/ethanol and the suspension was treated in ultrasound for 5 min. A drop of very dilute suspension was placed on a holey-carbon-coated copper grid and dried by evaporation at ambient temperature.
Transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and scanning transmission electron microscopy (STEM) were performed on a FEI Talos F200X microscope (Thermo Fisher Scientific, Waltham, MA, USA) operating at 200 keV. Images were recorded on a CCD camera with resolution of 4096 × 4224 pixels using the ‘User interface software package.’ An energy dispersive X-ray spectroscopy (EDX) system attached to the TEM operating in the STEM mode was used to analyze the chemical composition of the samples. High-angle annular dark-field (HAADF) image presented in the paper was captured in nanoprobe-TEM mode with a camera length of ~200 mm. All of the presented digital images were analyzed, but not processed.
The absorption coefficient of the light (α) of the newly synthesized nanocomposite was measured by ultraviolet-visible (UV-Vis) spectrophotometer Evolution 600 (Thermo Fisher Scientific, Waltham, MA, USA), in the electromagnetic spectrum range between 240 nm and 840 nm with the step of 1 nm and speed of 10 nm/min. Demineralized water was used as a reference during the measurements.

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.
