Research Field

We conduct research in the area of the physics of energy conversion and storage. The main topics include the design and implementation of functional materials and a better understanding and characterization of electrified interfaces. The material design is based on a bottom-up approach using input from electrochemical surface science and starting from model surfaces.

Microwave-assisted synthesis of graphitic Carbon Nitride (g-C3N4) Nanostructures for H2 production

Carbon is regarded as one of the main energy materials for various applications including heterogeneous catalysis for generation of so-called "solar fuels", and energy storage devices (batteries, supercapacitors etc). The incorporation of nitrogen to carbon was found to enhance the functional properties of carbon and hence has been studied extensively. Furthermore, carbon nitride (C3N4) is a nontoxic and metal-free material. In contrast to pure carbon, C3N4 is a semiconductor with a medium bandgap of around 2.7 eV. Research on graphite carbon nitride (g-C3N4) and related bulk/nanostructures has seen an enormous increase in the level of interest in recent years.

Generally, g-C3N4 has been synthesized by means of electrochemical deposition, arc‐plasma jet chemical vapor deposition, radio frequency magnetron sputtering, electron cyclotron resonance plasma sputtering etc. However, reported techniques have several drawbacks that are not desired for large-scale production such as cost, toxicity (in case of using templates and HF for removal) or their industrial unsuitability on account of the involvement of two molecular precursors at one time.

The aim of this project is the synthesis of the g-C3N4 catalyst for H2 fuel production by using microwave assisted techniques. For the synthesis of g-C3N4, mild acidic and basic solutions will be used. The purpose of using acidic and basic solutions is to engineer the nanostructures of g-C3N4 without any templates on large scale production. The obtained g-C3N4 nanostructures will be further studied for the optimization of the target properties of g-C3N4. Then the comparison will be carried out to study the properties of carbon nitride in different solutions. This will help in understanding the catalytic and other functional properties that are optimal for its use in the potential applications and to fabricate it on a pilot and industrial scale.
