PhD Student (f/m/d) in Chemistry

Kennziffer: EE 2019/7

The Helmholtz research group "
" studies new electrocatalyst materials and investigates the mechanisms of the conversion of carbon dioxide into valuable chemicals and fuels driven by renewable energy. The goal is to develop new strategies for transforming solar energy into versatile chemical forms while utilizing waste CO2 as a chemical feedstock, rather than emitting it into the environment.

The research group uses state-of-the-art synthesis and characterization tools, and takes advantage of the rich collaborative environment of the Helmholtz-Zentrum Berlin. The group is based at HZB-Wannsee but also conducts experiments at the BESSY II synchrotron and collaborates with local universities and research institutes.

Forschungsthema und Ziele

Topic: "Influence of semiconductor electrode–catalyst interactions on photoelectrochemical CO2 conversion"
The student will devise and execute experiments to investigate the roles of semiconductor structure (electronic structure, morphology, surface functionalization) in influencing the activity of photoelectrochemical CO2 reduction. The goal is to develop understanding of how semiconductor–catalyst interfaces influence product selectivity differently than metal–catalyst interfaces, and how the differences might be exploited to both study and control the CO2 reduction reaction.

Individual tasks of the student include (but are not limited to):

• Synthesize a variety of semiconductor photoelectrode materials (oxides, sulfides, Si nanowires).
• Perform (photo)electrochemical studies in both aqueous and non-aqueous environments.
• Evaluate CO2 conversion products using electrochemical methods coupled to product quantification techniques (GC, MS, HPLC, NMR).
• Characterize materials by microscopy and spectroscopy.

Anforderungen

• Completion of Master's degree in Chemistry, Materials Science, or closely-related field
• Strong knowledge and experience with electrochemical methods is required
• Good spoken and written English communication skills

Please upload the following documents with your application:

• Motivation letter (in English) describing your background and research interests
• Curriculum vitae (CV) listing your education, publications, research experience, and contact details for two references

Fixed term contract for 36 months. Payment is made in accordance with the collective agreement for public service (TVöD-Bund).
We strive to increase the proportion of female employees and are therefore particularly pleased to receive applications from women. Disabled applicants with equal aptitude are given preference.

Der Arbeitsvertrag ist über 36 Monate befristet. Die Bezahlung erfolgt nach dem Tarifvertag für den öffentlichen Dienst (TVöD-Bund).
Wir bemühen uns, den Anteil an Mitarbeiterinnen zu erhöhen und freuen uns daher besonders über Bewerbungen von Frauen. Schwerbehinderte Bewerberinnen/Bewerber werden bei gleicher Eignung bevorzugt eingestellt.

Sind Sie interessiert? Dann bewerben Sie sich bitte bis spätestens 24.03.2019.

Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) operates two large facilities for materials research: the neutron source BER II and the synchrotron source BESSY II, which provide deep insights into the structure of materials and the processes within complex systems. Other important focuses of HZB research are thin film photovoltaics and solar fuels. Each year around 3,000 scientists use the HZB infrastructure facilities.

SCIENCE + CAREER + DIVERSITY = HZB

... is the formula for our successful human resources policy. We offer wide-ranging internal and external training programs for our employees as well as a special support program for young scientists. Our family-friendly workplace policy includes flexible working hours and telework arrangements.
