Photocatalysis is an emerging green technology using the property of certain materials to trigger chemical reactions under light irradiation. Pollutant removal from water and air; hydrogen production by water splitting; high value chemical and fertilizer production based on CO2 capture are just a few among the potential applications of this promising technology. While some photocatalysts can only work under UV irradiation, others are efficient with visible light, making them even more interesting for future, large-scale applications. However, in all cases, the microstructure of the photocatalyst has a tremendous influence on its performance, because not only a large contact surface area is necessary, but specific crystallographic facets need to be favored as well.

The aim of this project is to optimize the microstructure of photocatalyst films based on various materials including ZnO, TiO2 or Bi-ferrites, the latter being able to work under visible light, and to perform tests of photocatalytic degradation of typical water pollutants. Large projects may include the design and manufacture of a test bench for outdoor demonstration.

 

During this project you are going to:

-Manufacture photocatalyst films on various substrates using green chemistry deposition techniques.

-Conduct characterization of your samples by means of X-ray diffraction, optical and electron microscopy, as well as various spectroscopy techniques.

-Conduct experiments on water pollutant degradation to evaluate the photocatalytic performance of your samples.

-Analyze your results using theoretical models and compare them with published data.

 

Learning objectives:

At the end of this project you will be able to:

-Explain the principles of photocatalysis and of its potential applications.

-Use various experimental characterization tools (X-ray diffraction, electron microscopy, thermal analysis, spectroscopy) and explain their basic principles as well as limitations.

-Critically evaluate your results.

-Draw links between processing parameters, microstructure and performance.

-Perform an efficient literature search and compare your own results to published data.

-Present your results to a scientific audience under conditions equivalent to an international conference.

-Write the draft of a scientific publication.
