Interfacial catalysis of peroxides for water decontamination: A critical review on fundamental origins and selective oxidation

Direct Electron Transfer-Driven Nontoxic Oligomeric Deposition of Sulfonamide Antibiotics onto Carbon Materials for In Situ Water Remediation

“…Even for pollutants with the same parent structure, differences in substitute may result in the diversity of the ratedetermining steps in kinetics. 55 Among these elementary steps, steps closely related to the pollutant properties are mass transfer and electron transfer processes (with the corresponding descriptors being XlogP3 and HOMO). Therefore, it was hypothesized that pollutants could be divided into two categories, with their kinetic rates determined by mass transfer and electron transfer, respectively.…”

“…Furthermore, the literature has indicated that the hydrophilicity of the pollutants determined their mass transfer process (Figure a), which subsequently influences the oxidation rate. , Therefore, XlogP3 emerged as a good descriptor for QSAR. However, a debate existed over which descriptor was more appropriate. , Additionally, although these two types of descriptors have frequently been employed in the study of QSAR for phenolic pollutants, limited research has been conducted on the more structurally complex SAs in oligomerization-based C-ISCO …”

“…However, the heterogeneous removal of pollutants based on the electron transfer mechanism involves multiple elementary steps. Even for pollutants with the same parent structure, differences in substitute may result in the diversity of the rate-determining steps in kinetics . Among these elementary steps, steps closely related to the pollutant properties are mass transfer and electron transfer processes (with the corresponding descriptors being XlogP3 and HOMO).…”

“…However, a debate existed over which descriptor was more appropriate. 53,55 Additionally, although these two types of descriptors have frequently been employed in the study of QSAR for phenolic pollutants, limited research has been conducted on the more structurally complex SAs in oligomerization-based C-ISCO. 32 As shown in Figure 4b, notable disparities were observed in the ranking of HOMO and XlogP3 values for SAs, suggesting that no obvious correlation existed between the two descriptors.…”
