Ionothermal carbon materials
… precursors employing and developing the ionothermal carbonization. During the ionothermal carbonization, a salt melt simultaneously serves as solvent and porogen. Typically, eutectic mixtures containing zinc chloride are employed as salt phase. The first topic of the present thesis …

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 …

Ionothermal Synthesis of High Silica Zeolites in Deep Eutectic Solvents (DES)
Phase-pure high silica zeolites have been synthesized using different deep eutectic solvents for the first time. ZSM-5 was made in tetrapropylammonium bromide/pentaerythritol. The reaction is affected by the amounts of seeding, water content, and organic structure-directing agent (SDA). Sodalite …

Fundamental research of the solvent role in the ionothermal synthesis of microporous materials
… in water. Then in 2004, a new method called ionothermal synthesis was invented by Dr. Morris and his colleagues, using ionic liquids (ILs) and eutectic mixtures as the solvent. In contrast to water, ILs and eutectic mixtures have negligible vapor pressure, thus making the use of high-pressure …

En route towards advanced catalyst materials for the electrocatalytic water splitting reaction
… strategies (wet chemistry in organic solvents, ionothermal reaction, gas phase reaction), one goal has been systematically pursued: to understand the driving mechanism of the growth. Moreover, deeper understanding of inherent properties and kinetic parameters of the catalytic materials has been …

On new allotropes and nanostructures of carbon nitrides
… a solvatory effect. At the close of this chapter ionothermal synthesis is seen established as a powerful tool to overcome the inherent kinetic problems of solid state reactions such as incomplete polymerisation and condensation in the bulk especially when the temperature requirement of the …

Lignin valorization
… the final carbon. The carbons were obtained by ionothermal treatment of the precursors in the presence of the eutectic salt mixture KCl/ZnCl2 Such synthesized carbons showed micro-, macro- and mesoporosity and were tested for their electrocatalytic activity towards the oxygen reduction reaction. …

Ionothermale Synthese funktioneller Kohlenstoffnitrid basierter Materialien
Die Doktorarbeit behandelt die Synthese Kohlenstoffnitrid basierter Materialien in eutektischen Mischungen bivalenter Metallchloride. Der Fokus liegt dabei auf ZnCl2-, SnCl2- und CoCl2-haltigen eutektischen Mischungen, in denen die Kondensation gebräuchlicher organischer Precursoren durchgeführt …
