Microwave effects in heterogeneous catalysis: Application to gas-solid reactions for hydrogen production

Due to the quest for more efficient production processes both from the energy and selectivity point of view, microwave irradiation has attracted significant scientific attention over the last three decades, as an alternative means of chemical activation. Over this period, striking process benefits, such as higher conversions and selectivities...

Electrochemical determination of hydrogen peroxide using Rhodobacter capsulatus cytochrome c peroxidase at a gold electrode

We describe the redox behaviour of horse heart cytochrome c (HHC) and Rhodobacter capsulatus cytochrome c peroxidase (RcCCP) at a gold electrode modified with 4,4?-bipyridyl. RcCCP shows no additional oxidation or reduction peaks compared to the electrochemistry of only HHC, which indicates that it most likely binds to HHC and results in a...

Chemoenzymatic cascade processes for sustainable organic synthesis

Chemical production processes often require wasteful and expensive isolation as well as purification of intermediates. Catalytic cascades offer a unique opportunity to eliminate these inefficient and polluting steps, in particular when carefully orchestrated, involving enzymes and chemocatalysts. This thesis describes our efforts towards a...

Transfer hydrogenations and kinetic resolutions

Chapter 1 is a review on homogeneous transfer hydrogenations. It shows the different reaction mechanisms involved for different types of catalysts. Additionally, the importance of the right choice of hydrogen donors and solvents is discussed. A wide range of compounds can be reduced in this way and the selectivity of these catalysts is very high...
