Title:
CO2 conversion by heterogeneous photocatalysis (2 PhD scholarships)
Research area and project description:
Humanity is starting to face the consequences of anthropogenic CO2 emission, and there is currently large focus on the development of carbon capture and utilisation technologies, which would enable conversion of carbon dioxide into valuable products. Photochemical CO2 reduction uses light as energy input for the reduction of CO2. Hence by using solar light or low-cost LED technology, CO2 from industrial gas emissions may be used as a C1 source for producing fuel or commodity chemicals, which are conventionally produced from fossil fuels. Light-driven CO2 conversion is challenging and often suffers from low conversion. Therefore, the development of improved catalysts is crucial for improving photocatalytic CO2 conversion.
The goal of this project is to use heterogeneous photocatalysis for CO2 conversion to products such as carbon monoxide or formate or even to ethylene or ethanol. The project will be conducted within the Carbon Dioxide Activation Center (CADIAC) at Aarhus University. CADIAC uses an interdisciplinary approach, e.g. photo-, electro-, and homogeneous catalysis, to target the challenge of catalytic CO2 reduction.
The project will be based on the development of novel hybrid organic-inorganic materials including two-dimensional materials, carbon materials, and metal-organic frameworks. Rational materials design will be applied to optimize the light absorption and catalytic properties of the materials towards their CO2 conversion properties. This includes tailoring of carbon based materials as light absorbers. Besides screening of the catalytic properties, the best performing materials will be characterized in depth using X-ray based techniques (including powder diffraction and X-ray absorption spectroscopy), electron microscopy, and spectroscopic methods in order to investigate the mechanism behind the CO2 conversion.
The PhD student will design and conduct synthesis of hybrid organic-inorganic materials by means of solvothermal as well as “wet-chemical” synthesis approaches. Moreover, the candidate will carry out systematic screening of CO2 conversion reactions including application of analytical techniques for product identification and quantification (e.g. gas- and ion chromatography). The PhD student will also perform structural characterization of selected materials. The candidate will work in an interdisciplinary environment, and the student is expected to stay 3-6 months in Germany during the studies.
Qualifications and specific competences:
Applicants to the PhD positions should have a Master’s degree in chemistry, chemical engineering, nanoscience or equivalent fields. The candidate should have strong experience with synthesis of inorganic, organic and/or hybrid organic-inorganic materials. Likewise, the applicant must have hands-on experience with some of the following techniques for characterization of materials and/or synthesis products: X-ray based techniques including powder diffraction, NMR spectroscopy, gas chromatography, and electron microscopy. Experience with catalysis is an advantage. Good English communication skills (oral and written) are required.
Place of employment and place of work:
The place of employment is Aarhus University, and the place of work is Interdisciplinary Nanoscience Center (iNANO), Gustav Wieds Vej 14, DK-8000 Aarhus C., Denmark.
iNANO, Interdisciplinary Nanoscience Center (www.inano.au.dk), was established in 2002 and at present is a major research and education center based at Aarhus University hosting 60 senior scientists, ~100 PostDocs and ~100 PhD students. The center combines expertise and faculty from Physics, Chemistry, Molecular biology and Medicine to carry out world class interdisciplinary research in Nanoscience and Nanotechnology. The center gives access to a broad range of infrastructure, tools and expertise including clean-room facilities. With a 5 year undergraduate nanotechnology programme and nanoscience graduate programme (www.inanoschool.au.dk) the center provides a full educational environment. In addition to the large base of basic research, the center has a large number of ongoing industrial projects and partnerships.
