The phase constitutions of BGFSO nanoparticles were characterized by X-ray diffractometry (XRD, Rigaku 2500, Japan) with Cu-Ka radiation operating at 40 kV and 20 mA. The scanning electron microscopy (SEM, JSM-6460, Japan) was used to study the morphology of BGFSO nanoparticles. The band-gap and photocatalytic properties of BGFSO nanoparticles were studied by UV-vis diffused reflectance spectra via UV- vis spectrophotometry (Hitachi UV-3310, Japan) with an integration sphere. The porosity and Brunauer-Emmett-Teller (BET) surface area of the samples were obtained from N2 sorption/desorption isotherms at 77 K by Quadrasorb-SI v. 5.06 (Quantachrome Instruments Corporation, USA). The photoluminescence spectra were measured on Horiba Scientific Fluoromax-4 spectrofluorometer using 300 nm excitation wavelengths.

The X-ray diffraction patterns of the samples were carried out on the Bruker X-ray diffractometer (XRD, D8 Advance) using Cu Kα. An Autosorb-iQA3200-4 sorption analyzer (Quantatech Co., USA) based on N2 adsorption/desorption was used to measure the Brunauer–Emmett–Teller specific (BET) surface area. The surface morphology and thickness of the Bi2O2CO3 samples were examined with a field emission scanning electron microscope (FESEM, Hitachi S4800), transmission electron microscope (TEM, JEM-2100F), and atomic force microscope (AFM, Dimension V, Veeco). The surface chemical valences of the Bi2O2CO3 catalyst were analysed with an ESCALAB 250 X-ray photoelectron spectroscope (XPS). The UV-visible diffuse reflectance spectra were measured with a Hitachi UV-3310. The photoluminescence (PL) spectra were collected on a Hitachi F4600 fluorescence spectrophotometer, using a Xe lamp (excitation at 365 nm) as the light source.
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.
