Oxidation of organic micropollutant surrogate functional groups with peracetic acid activated by aqueous Co(II), Cu(II), or Ag(I) and geopolymer-supported Co(II)

Urs von Gunten

Peracetic acid (PAA) in combination with transition metals has recently gained increasing attention for organic micropollutant abatement. In this study, aqueous Co(II), Cu(II), and Ag(I) were compared for their capacity to activate PAA. Co(II) outperformed ...

Evaluation of Photocatalysts for Water Splitting through Combined Analysis of Surface Coverage and Energy-Level Alignment

Alfredo Pasquarello, Francesco Ambrosio, Zhendong Guo

To examine whether suitable conditions occur for the water splitting reaction at their interfaces with liquid water, we determine the pH-dependent surface coverage for a series of semiconductors, including GaAs, GaP, GaN, CdS, ZnO, SnO2, and rutile and ana ...

Metal-Organic-Framework-Derived Co3S4 Hollow Nanoboxes for the Selective Reduction of Nitroarenes

Wendy Lee Queen, Emad Oveisi, Daniel Teav Sun, Shuliang Yang, Li Peng, Safak Bulut

MOF-derived Co3S4/CN hollow nanoboxes (CN=nitrogen-doped carbon) was used to catalyze the chemoselective reduction of nitroarenes to anilines under mild reaction conditions with H-2 as the reducing agent. The catalyst provides high conversion efficiencies ...

Atomic-level organization of vicinal acid-base pairs through the chemisorption of aniline and derivatives onto mesoporous SBA15

David Lyndon Emsley, David Benjamin Roger Antoine Gajan

The design of novel heterogeneous catalysts with multiple adjacent functionalities is of high interest to heterogeneous catalysis. Herein, we report a method to obtain a majority of bifunctional acid-base pairs on SBA15. Aniline reacts with SBA15 by openin ...

Reaction of bromine and chlorine with phenolic compounds and natural organic matter extracts - Electrophilic aromatic substitution and oxidation

Urs von Gunten, Eva Maria Rodriguez Franco

Phenolic compounds are known structural moieties of natural organic matter (NOM), and their reactivity is a key parameter for understanding the reactivity of NOM and the disinfection by-product formation during oxidative water treatment. In this study, spe ...

Structure-property relationships based on Hammett constants in cyclometalated iridium(III) complexes: their application to the design of a fluorine-free FIrPic-like emitter

Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod, Julien Edouard Frey

While phosphorescent cyclometalated iridium(III) complexes have been widely studied, only correlations between oxidation potential EOX and Hammett constant sigma, and between the redox gap (Delta E-REDOX = E-OX-E-RED) and emission or absorption wavelength ...

Reactivity of BrCl, Br2, BrOCl, Br2O and HOBr toward dimethenamid in solutions of bromide + aqueous free chlorine

Jeremy Samuel Arey, Peter Rudolf Tentscher

HOBr, formed via oxidation of bromide by free available chlorine (FAC), is frequently assumed to be the sole species responsible for generating brominated disinfection byproducts (DBPs). Our studies reveal that BrCl, Br-2, BrOCl, and Br2O can also serve as ...
