Growth, properties and photocatalytic degradation of congo red using Gd:ZnO thin films under visible light

Influence of Cu doping on the functionality of spray coated SnS2 thin films and its photocatalytic degradation of dyes and antibacterial activity

“…At 0, 6, 12, and 24 h intervals, 10 ml of microbial cells were taken out of each flask and mixed with 10 ml of broth solution. The mixture was then incubated at 37 °C for 24 h. The optical density of each flask was determined using a UV-vis spectrophotometer at 610 nm, and the number of living cells (CFU/mL) was counted after three repetitions to get the percentage of dead cells compared to the number of growing colonies at t = 0 [49].…”

“…The antibacterial properties of as-synthesized pristine SnS 2 , 2 at% Cu-doped SnS 2 , and 4 at% Cu-doped SnS 2 thin films were evaluated against Gram-negative bacteria, E. coli by employing a time-kill method under visible light irradiation [49]. The logarithm of the colony-forming units per milliliter (log 10 CFU/mL) against time was plotted to generate time-kill curves and compared with the control in the absence of light.…”

Magnetic hierarchical flower-like Fe3O4@ZIF-67/CuNiMn-LDH catalyst with enhanced redox cycle for Fenton-like degradation of Congo red: optimization and mechanism

“…Congo red (CR) is a type of anion diazo dye and the most periodically utilized one that could metabolize to the carcinogenic benzidine (Dang et al 2020). The preponderance of CR dye-containing wastewater induced by printing and dyeing industries causes deleterious impacts on the ecological system (sadek Kadari et al 2022). Thence, it is vital to treat such noxious effluents using an appropriate treatment manner before drainage into the environment (Hussein et al 2022, Sundararaman et al 2018.…”
