A new approach to optimize the synthesis parameters of TiO2 microsphere and development of photocatalytic performance

TiO2-CeO2 based composite materials and their application in photocatalysis: A short review

“…The BET results provided data on the textural properties of the materials prepared by authors F. K. Dokan and Kuru (Dokan & Kuru, 2021). The results obtained and presented by the authors revealed that the surface area increased with the increase in CeO2 content (Dokan & Kuru, 2021). It has been reported that a high surface area is a favourable parameter, as it facilitates/promotes the adsorption of pollutant molecules on the catalytic surface, therefore improving/enhancing photocatalytic ability (Dokan & Kuru, 2021, Wang et al, 2013.…”

“…This procedure was followed by a calcination process at 450° C (Ameen et al, 2014). F. K. Dokan and Kuru (Dokan & Kuru, 2021) reported preparing an ultrafine composite material based on TiO2-CeO2 using the following procedure. Firstly, TiO2 microspheres were prepared using the hydrothermal method.…”

“…Cerium nitrate ((Ce(NO3)3•6H2O) was used as a precursor for the preparation of ultrafine nano-spherical TiO2-CeO2 composites. The preparation of composites was achieved by the surfactant-supported sol-gel method, as mentioned above (Dokan & Kuru, 2021).…”

“…Numerous techniques and methods have been used by scientists for thorough characterisation of TiO2-CeO2-based composite materials such as X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), Brunauer-Emmett-Teller (BET) by N2 adsorptiondesorption measurements, Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), photoluminescence (PL) spectroscopy, field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), H2 temperature-programmed reduction (H2-TPR), high-resolution transmission electron microscopy (HRTEM) and others (Ameen et al, 2014;Dokan & Kuru, 2021;Stefa et al, 2020;Wandre et al, 2016;Zhang et al, 2018;).…”

“…K. Dokan and Kuru (Dokan & Kuru, 2021) thoroughly characterised the physicochemical properties of the TiO2-CeO2 prepared materials described earlier, which included techniques such as XRD, EDX, FE-SEM, BET, FTIR, etc. The BET results provided data on the textural properties of the materials prepared by authors F. K. Dokan and Kuru (Dokan & Kuru, 2021). The results obtained and presented by the authors revealed that the surface area increased with the increase in CeO2 content (Dokan & Kuru, 2021).…”
