Hydrothermal and ionothermal carbon structures
The needs for sustainable energy generation, but also a sustainable chemistry display the basic motivation of the current thesis. By different single investigated cases, which are all related to the element carbon, the work can be devided into two major topics. At first, the sustainable synthesis …

Functional nanostructured hydrothermal carbons for sustainable technologies : heteroatom doping and superheated vapor
The underlying motivation for the work carried out for this thesis was the growing need for more sustainable technologies. The aim was to synthesize a “palette” of functional nanomaterials using the established technique of hydrothermal carbonization (HTC). The incredible diversity of HTC was …

Ionothermal carbon materials
Alternative concepts for energy storage and conversion have to be developed, optimized and employed to fulfill the dream of a fossil-independent energy economy. Porous carbon materials play a major role in many energy-related devices. Among different characteristics, distinct porosity features, …

PEM-fuel cell catalysts from nanoscopic precursors : a comparative study
1. Minimising the amount of stabiliser In an systematic study it was found that the amount of applied (Octyl)4N-protecting agent can be reduced to 60% from the amount usually applied for the preparation of Pt/Ru organosol using a combination of (Octyl)4N[Bet3H] and Li[Bet3H] as reductants. Further, …
