Fabrication of SnWO4/ZnFe-layered double hydroxide composites with enhanced photocatalytic degradation of methyl orange

Ultrasound Assisted Synthesis of Gadolinium Oxide-Zeolitic Imidazolate Framework-8 Nanocomposites and Their Optimization for Photocatalytic Degradation of Methyl Orange Using Response Surface Methodology

“…After 40 min, the MO photocatalytic degradation efficiency decreased when the MO concentration increased from 0.0630 to 0.0105 mM (Figure 6c). Within the experimental range, the pseudo-first-order rate constant k 1 decreased with an increase in the MO concentration based on Equation (10) [3]. These results indicate that the absorption of light on the photocatalyst surface decreased at higher concentrations.…”

“…In Figure 6b, the effect of the photocatalyst concentration was investigated by varying only the photocatalyst dose from 0.1 g/L to 0.3 g/L while the other conditions remained the same. Increasing the concentration of the photocatalyst in the MO solution may decrease the transmission of light [3]. Therefore, excess photocatalyst in solution could interfere with the photocatalytic degradation of the MO solution [36].…”

“…These dyes are hazardous to the environment if they are not destroyed and cause serious pollution [2]. Therefore, it is necessary to degrade such organic dye pollutants [3].…”

“…According to their raw materials, process principles, and pollutant characteristics, dye wastewater treatment methods can be classified into various categories, which include physical adsorption, membrane separation, biodegradation, electrochemical treatment, and photocatalysis [3]. The use of advanced oxidation processes (AOPs) is a major pathway for the near-ambient degradation of wastewater pollutants because the waste water pollutants can be degraded almost completely [4].…”

Sonochemical synthesis of ZnCo2O4/Ag3PO4 heterojunction photocatalysts for the degradation of organic pollutants and pathogens: a combined experimental and computational study

“…8,9 These issues can be resolved by designing visible-light-active photocatalysts or via a combination of different materials to build a heterojunction/heterostructure. 7,10…”
