Functional Materials


Solid materials with a given functionality are of relevance for many fields in chemical research. Surface functionalities are of specific interest and determine the properties of materials for processes that proceed at the interface of a solid and a fluid. Typical processes are heterogeneously catalyzed reactions, adsorption processes, and electrochemical reactions. Crucial factor for efficient processes are high specific surface areas that can be realized either by generation of pores in a solid or by formation of nanoscopic particles.

Research Topics:

Adsorption and diffusion processes are strongly affected by the pore systems and surface properties of nanoporous materials. Physical adsorption on solids is determined by interaction of molecules in the fluid phase with a given surface. Pore geometries and surface functionalities ... [more]
High surface area materials serve as catalysts or supports for active species. There are typically synthesized via precipitation, sol-gel processing, or flame processes. “Exotemplating” is a versatile alternative, e.g., using porous carbon matrices as hard templates. The pores of the carbon matrix... [more]
Solids with ordered mesopore arrangement can be synthesized either via soft- or hard-templating methods. Typical materials that are obtained via soft-templating are MCM-41 or SBA-15 silicas. Amorphous silica walls are condensed ... [more]
Irradiation of a semiconductor photocatalyst with light of appropriate wavelength results in the excitation of an electron from the valence band into the conduction band, leaving a positively charged hole in the valence band. This electron then ... [more]
Zeolites comprise a class of crystalline, microporous solids. They are mainly based on aluminosilicates, the structure of which are formed by corner-sharing SiO4 and AlO4 tetrahedra. Presence of three-valent ... [more]
