The infrared spectra are either collected on a PerkinElmer Spectrum two spectrometer or on a Bruker Alpha II spectrometer, both equipped with a diamond ATR-crystal.
Spectrum two spectrometer
Manufactured by Bruker
The Bruker Spectrum Two is a high-performance Fourier Transform Infrared (FTIR) spectrometer. It is designed to provide accurate and reliable infrared spectroscopic analysis across a wide range of applications. The Spectrum Two features a robust and compact design, and it is capable of analyzing solid, liquid, and gas samples.

The UV-Visible absorption spectra were recorded using Systronics Double beam Spectrophotometer 2203. The asprepared Fe 3 O 4 @trp, Fe 3 O 4 @trp@Ir nanocatalysts were characterized by Fourier transform infrared spectroscopy (FTIR, Perkin Elmer Spectrum Two spectrometer) and X-ray diffraction (XRD, Bruker Model D8-Advance, Cu anode, 40 kV, 40 mA). The particle size and surface morphologies were obtained using transmission electron microscopy (TEM, JEOL JEM-F200); eld emission scanning electron microscopy (FESEM, Model JSM6100 Jeol). The elemental composition was determined by X-ray photoelectron spectroscopy (XPS, Physical Electronics, and Model PHI 5000 VersaProbe III).
The speci c surface areas of Fe 3 O 4 @trp@Ir nanocatalyst were determined by Brunaeur-Emmett-Teller (BET, Quantachrome). A vibrating sample magnetometer (VSM, Lake Shore Model-7410 Series) was used to determine the magnetic of synthesized nanocatalysts. The zeta potential of nanoparticles was measured by Zeta potential analyzer (Malvern Zetasizer Nano ZS).

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.
