The mission of the Renewable Energy Research Group is to understand the fundamental principles governing the catalytic conversion of renewable energy carriers in thermal, photo- and electrochemical reactions and to design novel heterogenous catalysts for these processes. Several unique techniques are applied for our efficient research activity, such as combinatory and high throughput techniques.

Combinatory and High-throughput Techniques – Time- and Cost-efficient Research

Application of combinatorial methods means a special design of experiments for optimization purpose in practice. All the experimental variables are changed simultaneously, leading to design a large number of experiments to be accomplished in parallel by High-throughput Experimental Techniques. In order to reduce the number of experiments, different statistical and data mining tools are applied to reveal cross-effects between the different modifiers and correlations between composition and catalytic results. Our laboratory is equipped with devices in which we are able to prepare and characterize 16 samples simultaneously, such as a 16-channel tubular reactor system or a microwave oven with 16 autoclaves.

Fuel Cells  –  Clean Energy Production

The decades of research activity in the fields of catalysis and material science provide a firm scientific ground to develop novel fuel cell electrocatalysts. The most compelling practical needs of the real-life application, namely reducing the price and increasing the durability are approached by using novel nanomaterials, such as electro conductive mixed oxides or several carbonaceous materials (graphenes, carbon nanotubes and mesoporous carbons). The research and development are supported by a wide range of state of art experimental devices to characterize the structure and catalytic performance of the systems. One of our greatest strengths is the use of high-throughput methods and customized, individualistic solutions for effective and successful research and development.

Pyrolysis – Waste Management

The pyrolysis of biomass and waste plastics is a promising way of environmental-friendly upgrading of solid wastes to gain valuable products such as feedstocks or fuels. During decades of research activity the thermal properties and pyrolysis processes of biomass, synthetic polymers and plastics have been studied in details in our laboratory. Our research activities focus mainly on the thermal and thermocatalytic decomposition of macromolecules, on the reactions taking place during pretreatment processes (such as torrefaction), moreover on the upgrading of pyrolysis oils over solid catalysts.
