Improved photocatalytic activity of dysprosium-doped Bi2O3 prepared by sol–gel method

Comparative study on photocatalytic performances of crystalline α- and β-Bi2O3 nanoparticles under visible light

“…and preparation processes have demonstrated the strong correlation between the synthesis procedure of Bi 2 O 3 and its photocatalytic activities [36]. In order to take the advantage of above facts, sol-gel and hydrothermal methods were carried out with operational simplicity [20,37,38]. Herein, a-and b-Bi 2 O 3 nanoparticles were successfully synthesized using sol-gel and hydrothermal methods in the presence of either urea or polyethylene glycol.…”

A New Photocatalyst Bismuth Oxo Citrate: Synthesis, Characterization, and Photocatalytic Performance

“…The specific surface area (SSA) has a significant influence on the photocatalytic performance, because the photocatalytic process mainly occurs at the surface of photocatalyst. With the increase of SSA, the number of active sites is greater and photocatalytic performance is enhanced (Li et al, 2013;Li et al, 2014). The N 2 adsorption/desorption isotherm of bismuth oxo citrate according to the IUPAC classification ( Figure) belongs to type IV.…”

“…In recent years, many contributors reported that photocatalysts based on bismuth compounds, such as Bi 2 O 3 , BiVO 4 ,B i 2 WO 6 , BiOBr, BiOI, Bi 6 O 6 (OH) 3 (NO 3 ) 3 Á 1.5 H 2 O, and Bi 2 O 2 CO 3 ,have high photocatalytic activity (Li et al, 2013;Li et al, 2014;Liang et al, 2016;Saison et al, 2011;Shang et al, 2009;Wang et al, 2016;Wu et al, 2013;.…”

BiOCl dispersed on NiFe–LDH leads to enhanced photo-degradation of Rhodamine B dye

“…Bismuth oxyhalides and other Bi compounds such as BiOX (X = Cl − , Br − , I − ) (Li et al, 2013b;Liu et al, 2011), Bi 12 O 17 Cl 2 (Xiao et al, 2013), Bi 2 WO 6 (Ma et al, 2013), BiVO 4 (Li et al, 2013a), Bi 2 OCO 3 (Cheng et al, 2010), BiPO 4 , Bi 2 O 3 (Li et al, 2013c), and p-BiOI/n-ZnTiO 3 (Reddy et al, 2013) have been developed and widely used in the treatment of wastewater from printing and dyeing industries. The Bi-based materials have good photocatalytic performance and hence, they could become the materials of choice as photocatalytic catalysts.…”
