TL;DR: In this article, a modified glassy carbon electrode was used for the characterization of catalytic catalytic activities in a GCE and chitosan modified GCE, and the peak-to-peak potential separations between catechol (CT), resorcinol (RS) and hydroquinone (HQ) were obtained in their ternary mixture.

Highly sensitive and simultaneous determination of hydroquinone and catechol at poly(thionine) modified glassy carbon electrode
TL;DR: In this paper, a poly(thionine)-modified glassy carbon electrode (GCE) was used for the simultaneous and quantitative detection of hydroquinone (HQ) and catechol (CT).
Journal ArticleDOI
Simultaneous determination of catechol and hydroquinone using electrospun carbon nanofibers modified electrode
TL;DR: In this paper, the simultaneous determination of dihydroxybenzene isomers (catechol (CC) and hydroquinone (HQ)) was investigated using cyclic voltammetry (CV) and DPV at electrospun carbon nanofiber-modified carbon paste electrode (ECF-CPE) in 0.1 M PBS (pH 7.0) solution.

Simultaneous Determination of Hydroquinone and Catechol at an Activated Glassy Carbon Electrode
TL;DR: In this paper, a selective and very simple electrochemical method, based on anodization of a glassy carbon electrode (GCE), was developed for the simultaneous detection of hydroquinone (HQ) and catechol (CT).

Phenol hydroxylation using Fe-MCM-41 catalysts
TL;DR: In this paper, a high-ordered iron-containing mesoporous material, Fe-MCM-41, with 0.5-4 Fe/Si mol% loading was prepared and characterization was performed using XRD, SEM/TEM, EDS, N2-sorption, and FT-IR and UV-vis spectroscopies.

Reactions of low-valent transition-metal complexes with hydrogen peroxide. Are they "Fenton-like" or not? 1. The case of Cu+aq and Cr2+aq
TL;DR: In this paper, a thermodynamic analysis of the Fenton reaction and Fenton-like reactions points out that their detailed mechanisms involve the formation of a transient complex between the low-valent cation ML/sub m-1//sup n/ and hydrogen peroxide of the type H/sub 2/O/H/sup /minus//.

Hydroxylation of phenol with hydrogen peroxide on EUROTS-1 catalyst

TL;DR: The catalytic performance of a standard titanium molecular sieve catalyst, EUROTS-1, has been evaluated at four European universities as discussed by the authors, and the results showed that the calcination conditions of the catalyst, the use of internal standards, and the nature and the amount of the solvent added to the reaction mixture were major factors determining phenol conversion, product selectivity and hydrogen peroxide product yield.
