Proton Pump for O2 Reduction Catalyzed by 5,10,15,20- Tetraphenylporphyrinatocobalt(II)

Hubert Girault, Bin Su, Fengping Li, Raheleh Partovi Nia, Zdenek Samec

The role of 5,10,15,20-tetraphenylporphyrinatocobalt(II) ([Co-(tpp)]) as a catalyst on molecular oxygen (O2) reduction by ferrocene (Fc) and its two derivatives, 1,1’-di-methylferrocene (DFc) and decamethylferrocene (DMFc) at a polarized water¦1,2-dichloro ...

Detection of hydrogen peroxide produced at a liquid/liquid interface using scanning electrochemical microscopy

Hubert Girault, Fernando Cortes Salazar, Bin Su, Raheleh Partovi Nia

Scanning electrochemical microscopy (SECM) was used to monitor in situ hydrogen peroxide (H2O2) produced at a polarized water/1,2-dichloroethane (DCE) interface. The water/DCE interface was formed between a DCE droplet containing decamethylferrocene (DMFc) ...

Generation of OH radicals at palladium oxide nanoparticle modified electrodes, and scavenging by fluorescent probes and antioxidants

Hubert Girault, Junqiu Liu

The reduction of palladium oxide nanoparticles in the presence of hydrogen peroxide or dissolved oxygen gives rise to a catalytic reduction current dependent on the hydrogen peroxide concentration or the oxygen concentration. Using terephthalic acid as an ...

Reactivity of electrogenerated free hydroxyl radicals and activation of dioxygen on boron-doped diamond electrodes

Agnieszka Kapalka

Synthetic boron-doped diamond (BDD) thin film is an electrode material with high chemical and dimensional stability, low background current and a very wide potential window of water stability. Upon anodic polarization, BDD generates hydroxyl radicals that ...

Nitrous Oxide Decomposition on the Binuclear $\left$ Center in Fe-ZSM-5 Zeolite

The reaction mechanism for nitrous oxide (

{N}_{2}O

) direct decomposition into molecular nitrogen and oxygen was studied on binuclear iron sites in Fe-ZSM-5 zeolite using the density functional theory (DFT). Starting from the hydroxylated bi-iron complex ...

Study of N2O decomposition over Fe-ZSM-5 with transient methods

Petra Prechtl

Nitrous oxide is the third most important gas contributing to global warming and its concentration in the atmosphere is still on the rise. Nitric acid production represents the largest source of N2O in the chemical industry, with a total annual emission of ...

Modeling Cryptosporidium parvum oocyst inactivation and bromate in a flow-through ozone contactor treating natural water

Urs von Gunten

A reactive transport model was developed to simultaneously predict Cryptosporidium parvuum oocyst inactivation and bromate formation during ozonation of natural water. A mechanistic model previously established to predict bromate formation in organic-free ...

Nanofibres de carbone sur filtre métallique comme support catalytique structuré

Pascal Tribolet

The main objectives of this work are 2-fold : The development of a novel type of composite material based on carbon nanofibers supported on sintered metal fibers filters (CNF/SMF) and to explore the use of this material as a catalytic support for a model r ...

Chemical and electrochemical promotion of supported rhodium catalyst

Olena Baranova

The chemical and electrochemical promotion of highly dispersed nanofilm Rh catalysts (dispersion: about 10 %, film thickness: 40 nm) has been investigated for the first time. To this end Rh metal was sputter-deposited, either on a purely ionic conductor (8 ...
