Theoretical and experimental study of La/Ni co-doped SrTiO3 photocatalyst

Optical Properties of Nano–Structured ZnO : Sn Powders Prepared in a Micro Drop Fluidized Reactor

“…A similar trend was also observed in preparing ZnO : Sn film (Zegadi et al, 2014). In addition, the electronegativity around the Zn 2+ ions could decrease but the ionic strength of cation increases by replacing some Zn 2+ by Sn 4+ ions, which leads to the decrease in the crystallite size with increasing Sn 4+ content (Jia et al, 2010;Li et al, 2010). Figure 5 shows the DRS analysis of ZnO : Sn powders.…”

“…In order to provide prepared materials with new functions and characteristics, the reaction conditions and circumstances should be controlled (Song and Kang, 2000;Zhang and Li., 2003;Zhang et al, 2005;Li et al, 2010). In the present study, thus, the micro drop fluidized reactor was adopted to prepare ZnO : Sn powders by means of a one-step continuous process.…”

Synthesis, characterization and photocatalytic activity of nano sized undoped and Ga doped SrTi0.7Fe0.3O3 for 2,4,6-trichlorophenol photodegradation

“…60% photocatalytic degradation of methylene blue (MB) was obtained using Cr/ST under visible light irradiation for 3 h [26]. La/Ni co-doped ST exhibited improved degradation of MB [27]. 100% Malachite green was degraded under visible light irradiation for 1 h using Ni, La codoped ST calcined at low temperature [28].…”

“…The degradation is higher than that obtained by self-degradation or using commercially available photocatalyst (Degussa P25). 66% of the MBsolution attained orange dye was degraded by the Cu doped ST nanoparticles for 2 h under visible light irradiation [27]. The Cr, Lacodoped ST nanoparticles exhibited an enhanced photocatalytic activity for the degradation of Rhodamine B (RhB) under sunlight irradiation [30].…”

Effect of crystallization on the band structure and photoelectric property of SrTiO3 sol–gel derived thin film

“…Thus, numerous studies of band-gap engineering have been devoted to modify its band structure such as doping with metal and nonmetal ions [7e9] and compositing with other function materials [10,11] to improve its solar light absorption. Based on the defect chemistry principle [12e14] and band theory [15,16], the semiconductor characteristics of modified STO are discussed. It is well known that the formation of positively charged oxygen vacancies [17e19] makes the pure STO behave as an n-type semiconductor.…”
