Decontamination and disinfection of wastewater by photocatalysis under UV/visible light using nano-catalysts based on Ca-doped ZnO

Influence of Inductive Effect in Organic Residuals Content in IZO Thin Films and the Performance on the Behavior of MIS Capacitors on Plastic

“…This characteristic is commonly reported in oxide semiconductors [8]. Figure 1b shows the Raman spectra of the films where vibrational modes were found at 116, 374, 434, 573, 654, 812 and 1110 cm −1 corresponding to modes E2(low), A1(TO), E2(high), E1(LO), E1(TA+LO), E2(high)-E2(low) and A1(2LO), respectively [9][10][11][12][13]. The E2(low) mode is associated with vibrations of the Zn sublattice, and the high E2(high) mode is caused by vibration of oxygen atoms, whereas the E1(LO) mode is related to the vibrations of Zn atoms [9].…”

Development of a rapid method for assessing the efficacy of antibacterial photocatalytic coatings

“…Applications where they may be useful include hospital environments (Reid et al, 2018;Priyadarshini et al, 2020), decontamination and remediation of water (Ioannou-Ttofa et al, 2019;Oliveira et al, 2019;Redfern and Enright, 2020), highfrequency contact surfaces (Kim et al, 2018), and in air purification systems (Mohamed and Awad, 2020). However, the translation of these reports to real-world systems may be limited by several factors.…”

A Review of the some aspects for the development of ZnO based photocatalysts for a variety of applications

“…It should be noted that the photocatalytic activity of doped ZnO nanoparticles depends on various factors, such as phase purity, surface area, crystallite size, nature of the alloying substances and the production method [35]. Metals such as Al [35][36][37], Ca [38,39], Ag [40][41][42], Mn [43], Mg [44], Sr [45], Fe [46], V [47] and Ce [48] is now actively used as dopants to improve the photocatalytic activity of ZnO. For example, in [49] it was shown that the sol-gel synthesized, undoped and doped Ca and Al/Ca ZnO NP have a spherical shape with a crystallite size of 26.09 nm, 25.23 nm and 24.5 nm, respectively.…”
