Facile synthesis of nanostructured monoclinic bismuth vanadate by a co-precipitation method: Structural, optical and photocatalytic properties

Effect of pH on visible-light-driven photocatalytic degradation of facile synthesized bismuth vanadate nanoparticles

“…Our research team has previously reported a paper on BiVO 4 nanoparticles synthesized for different postcalcination treatment (450, 550 and 650°C) by co-precipitation method [29] and in this present work, the effect of synthesizing pH conditions over the photocatalytic properties of BiVO 4 nanoparticles was prepared by lowcost and time-consuming co-precipitation method. The structural, morphological, chemical state analysis and optical properties of the synthesized BiVO 4 nanoparticles were investigated using x-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-vis, Raman spectroscopy, x-ray photoelectron spectroscopy (XPS), photoluminescence and photocatalytic studies.…”

“…From the Raman peaks, the formation of single-phase BiVO 4 was in accordance with the XRD patterns. The broad peak at 355 cm −1 approves the symmetric deformation modes of the VO 4 3− tetrahedron [29]. The bond length of the vanadium (V) and oxygen (O) in BiVO 4 was calculated using the relation [29];…”

“…The optical properties of a semiconductor have an important role in the enhancement of electronic structure and photocatalytic activity. The optical absorbance was calculated from diffused reflectance spectra (Kulbelka-Munk units) [29];…”

Hybrid high‐porosity rice straw infused with BiVO4 nanoparticles for efficient 2‐chlorophenol degradation

“…Aside from the adsorption process, the photocatalytic degradation of environmental pollutants using visible‐light driven semiconductor photocatalysts has also attracted considerable attention over the past few years. Photocatalysts such as bismuth vanadate (BiVO 4 ) with a narrow band gap (2.4 eV) are popularly known as excellent visible‐light‐driven materials, which allow activation by visible light and sunlight irradiation . However, their low surface area and the porosity of single‐phase BiVO 4 limit their application as photocatalysts.…”

A Fair Comparison Between Bismuth Catalysts for Application in Photodegradation Under Visible and Solar Light

“…The photocatalytic activity of these catalysts has been widely studied and improved through various methods. Among them are hydro/solvothermal Lin et al, 2014;Wu, D. et al, 2016), sol-gel (Wu et al, 2010;Zhang et al, 2010a;Zhang et al, 2010b), ultrasound (Zhou et al, 2006;Zhou et al, 2007;Dong et al, 2014) and coprecipitation (Alfaro and Martínez-De La Cruz, 2010;Ravidhas et al, 2015). The hydro/solvothermal method is the most widely used, primarily due to its low cost, simplicity, low temperatures and short reaction time.…”
