Nexus ft ir spectrophotometer

FT-IR spectra using KBr discs were generated using a Nexus FT-IR spectrophotometer (Thermo Nicolet, Madison, USA).

X-ray diffraction (XRD) patterns were obtained on a D/MAXRBX-ray diffractometer (Rigaku, Japan). Morphological analysis was performed with an S-4800 field emission scanning electron microscope (FESEM) (Hitachi, Japan) with an acceleration voltage of 10 kV. TEM/HRTEM image was conducted using a JEM-2100F transmitting electron microscope. Raman spectra were collected using an INVIA spectrophotometer (Renishaw, UK). Fourier Transform Infrared spectra (FTIR) were acquired using a Nexus FT-IR spectrophotometer (Thermo Nicolet, America). X-ray photoelectron spectroscopy (XPS) measurements were done on a KRATOA XSAM800 XPS system with Mg Kα source. All the binding energies were referenced to the C1 s peak at 284.8 eV for the surface adventitious carbon. The amount of Fe(III) in Fe(III)/rGO-TiO₂ was performed on an atomic absorption spectrometry (GBC AVANTA-M, Australia). UV–vis absorption spectra were obtained using a UV–visible spectrophotometer (UV-1240, SHIMADZU, Japan).
