The crystal structures and phase data of samples could be determined by X-ray diffractometry (XRD) (D/MAX2500 PC, Rigaku Corporation, Tokyo, Japan). The morphologies and composition of the samples could be investigated by transmission electron microscopy (TEM) (JEM-2010, JEOL Ltd., Akishima, Japan), energy dispersive X-ray spectroscopy (EDX) (s-4800, Hitachi, Chiyoda, Japan), and scanning electron microscopy (SEM) (s-4800, Hitachi, Chiyoda, Japan). The spectrofluorometer (f7000, Hitachi, Chiyoda, Japan) could be used to investigate the separation efficiency of photo-induced charge for powdered samples. The Perkin Elmer System 2000 infrared spectrometer provided the Fourier transform infrared (FTIR) spectra (Perkin Elmer, Shanghai, China), with KBr as the reference sample. The spin trapping electron spin resonance (ESR) measurements were performed on a Bruker JES FA200 ESR spectrometer (Oubeier, Beijing, China). The electrochemical and photoelectrochemical measurements were performed via a three-electrode quartz cell system. A CHI 660B electrochemical system (Shanghai Chenhua Instrument Corp., Shanghai, China) was used to record the photoelectrochemical results.

X-ray powder diffractometer (Shimadzu XRD-7000) was used to analyse the crystallographic properties of the catalyst. X-ray photoelectron spectroscopy (XPS) was obtained using PHI-5400 (America PE) 250 xi system. The morphology of the sample was analysed by scanning electron microscope (SEM, JSM-6700F) and transmission electron microscope (JEM-2100) (Japan electronics). Energy disperse X-ray (EDX) was performed using a field emission scanning electron microscope (JSM-7610F) to analyse the samples elemental features. The photoluminescence (PL) spectra were measured with an FLS 980 Series of Fluorescence Spectrometers (UK). The UV-Vis diffuse reflectance spectra (UV-Vis-DRS) was measured on UV-2550 UV-Vis Spectrophotometer. The electron spin resonance (ESR) spectra were examined on a Bruker model ESR JES-FA200 spectrometer.

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.
