Selective Formic Acid Decomposition for High-Pressure Hydrogen Generation: A Mechanistic Study

Paul Joseph Dyson, Gabor Laurenczy, Ning Yan, Céline Fellay

A homogenous catalytic system has been developed that efficiently and selectively decomposes formic acid into hydrogen and carbon dioxide. [Ru(H2O)6]2+, [Ru(H2O)6]3+ and RuCl3·xH2O are all excellent precatalysts in presence of TPPTS (TPPTS=meta-trisulfonat ...

Er-Yb waveguide amplifiers in novel silicate glasses

Jana Jágerská

A set of novel silicate glasses containing ZnO and co-doped with Er3+ and Yb3+ was designed as substrates for optical waveguide amplifiers. Characterized by exceptionally low up-conversion, minimum Er concentration quenching and high mechanical as well as ...

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 ...

The heterogeneous interaction of trace gases on mineral dust and soot

Federico Karagulian

The present thesis work deals with the investigation of the heterogeneous reactions involving nitrate radical (NO3), dinitrogen pentoxide (N2O5) and ozone (O3) on surrogates of atmospheric mineral dust particles characteristic of the troposphere. An additi ...

Hydroxylamine decomposition in the presence of iron studied by calorimetry, online mid-IR and UV-vis spectroscopy

Julien Léo Billeter, Konrad Hungerbühler

Recent explosions at two chemical plants, one in the United States and one in Japan, involving hydroxylamine manufacture underline the lack of mechanistic understanding about this industrially relevant compound. The basic chemical properties of hydroxylami ...

Role of adsorbed NO in N2O decomposition over iron containing ZSM-5 catalysts at low temperatures

Albert Renken, Lioubov Kiwi

Transient response and temperature-programmed desorption/reaction (TPD/TPR) methods were used to study the formation of adsorbed NOx from N2O and its effect during N2O decomposition to O2 and N2 over FeZSM-5 catalysts at temperatures below 653 K. The react ...

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 ...
