The photocatalytic phenol degradation mechanism of Ag-modified ZnO nanorods
, 2020Photocatalysis, as a potential green technology, can effectively degrade organic pollutants. The changes of the intermediate products in the photocatalytic degradation process of pollutants are particularly important for studying the degradation ...

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1985
The acidities of 12 substituted phenols (pKBNa relative to the pKBNa of HClO4) and the formation constants of the corresponding homocomplexes, KAHA, in benzonitrile have been determined from e.m.f. measurements. Comparison with previous results reveals that the stability of homocomplexes increases in aprotic solvents in the order acetonitrile ...

Phenol and substituted phenols AOPs remediation
Journal of Hazardous Materials, 2005The oxidation of phenol and two substituted species (4-nitrophenol and 4-chlorophenol) has been carried out by means of the O3, UV-vis, O3+UV-vis, TiO2+UV-vis, O(3)+UV-vis+TiO2 and O3+TiO2 systems. From UV-vis experiments, the quantum yield of these organics has been calculated (0.018, 0.005 and 0.017 mol per Einstein for phenol, 4-nitrophenol and 4 ...

Phenol Peeling and the History of Phenol Peeling
Clinics in Plastic Surgery, 1998Historically, phenol peeling has been embraced by plastic surgeons as the method of choice for improving the appearance of coarse facial rhytides. The principal advantage of phenol peeling is its predictability: it requires no pretreatment regime. This article details the technical aspects of phenol peeling, its uses and limitations, as well as methods

Microbial Degradation of Phenol and Phenolic Compounds
2021Phenol and phenolic compounds play an essential role in various modern-day industries. However, due to the toxic and recalcitrant nature of phenolic compounds, these compounds have a detrimental effect on the environment and aquatic life. In the recent past, different physicochemical methods have been employed by various researchers for phenol ...

Catalytic ethoxylation of phenol and phenol derivatives
Reaction Kinetics and Catalysis Letters, 1980The kinetics of catalytic mono- and polyethoxylation of phenol, p-cumyl-phenol and p-isooctylphenol have been studied in the presence of strongly basic anion exchanger Wofatit SBW in hydroxy form. The influence of substituents on the rate has been investigated and the mechanism of the reaction is discussed.
