Research

Renewable energy conversion and storage are relevant topics in applied research today, since the use of non-fossil energy sources is essential for the reduction of CO2 emissions. Solar and wind energy harvesting combined with chemical energy storage in batteries or fuels like hydrogen are essential processes, which need to be improved in efficiency, long-term stability and scalability. Our goal is to contribute to the development of cost effective scalable solutions for energy conversion and storage.

Modified H2V3O8 to Enhance the Electrochemical Performance for Li‐ion Insertion: The Influence of Prelithiation and Mo‐Substitution

V sites in H2V3O8 were substiuted by Mo. The needle-shaped nanostructure was preserved combining a soft chemical synthesis approach with a hydrothermall process. Together with chemical prelithiation this modification lead to 40 % capacity increase (312 mAh g-1) and to improved stability with respect to H2V3O8.

Scaling Up Electrodes For Photoelectrochemical Water Splitting

A scalable fabrication process for particle-based electrodes for solar water splitting was developed. Demonstrator-size photoanodes exhibited complex performance changes related to electrode size. Scale-up of photoelectrochemically active electrodes needs careful consideration in terms of size and device geometry.

Breakthrough in solar water splitting

In May, 2020, Simone Pokrant published a comment in the Nature science magazine’s News & Views section with her view on a breakthrough in catalyst design by Takata et al. that might accelerate the development of large-scale processes for producing hydrogen from water using sunlight.

Nature is one of the most quoted science magazines with the highest impact factor in its category.

Her article can be found here.   

The nature podcast corresponding to the work of Takata et al. is linked here.

We are pleased that the following students are currently writing their bachelor thesis with us:

Students Topic
Czternastek, Hubert Vanadylphosphate as energy storage material for metal-ion-batteries
Huber, Andreas Conductive networks for battery electrodes
Klammer, Peter Fabrication of photoanodes by scaleable processes
Praxmair, Jakob Improving the material properties of a photocatalyst for solar water splitting
Zern, Christoph Hydrated vanadium oxides as energy storage material for Ion-batteries

 

 

Talent internship

Once again, the student Cornelia Shtepani joined the group of Prof. Simone Pokrant as an intern in August, 2020. In context of the FFG student internship programme, she could experience a scientist's every day life and get further insight into the topic of preparation and characterization of photocatalysts for solar water splitting.  

Article "Scaling Up Electrodes For Photoelectrochemical Water Splitting" On Frontcover Of "ChemSusChem"

Barrierefreiheit: Kurzbeschreibung des Bildes

Great success for the Functional Materials Group. Their article "Scaling Up Electrodes For Photoelectrochemical Water Splitting" (see section Latest Publications) was selected as front cover story in the science magazine "ChemSusChem". The magazine, released by the Wiley-VCH publishing house (Germany) on behalf of ChemPubSoc Europe, publishes scientific articles concerning interdisciplinary research at the interface of chemistry, material science, sustainability and energy. It has an impact factor of 7.7 and is ranked at place 18 of 157 magazines worldwide in the field of interdisciplinary chemistry.

    During games when there are no fans in local football stadiums, deep acoustic insights into the inner workings of coaches can clearly be heard in TV broadcasts, due to the lack of background noise.Nevertheless, emotional outbursts and arguments among players and coaches have decreased considerably overall, in corona-related “behind closed door matches". Salzburg researchers calculated this using the example of games at FC Red Bull Salzburg. In contrast, more goals were scored across Austria.

    The new edition of the journal for practical philosophy is now online, with its finger on the pulse is also takes into account one topic that is shaping us like no other:the Corona pandemic. It is one of the two main focuses of the issue and its considerable scope not only reflects the importance of this topic, but also the real need to reflect philosophically and ethically on the diverse consequences of this pandemic.
    With the PLUS Talk, a new form of communication was introduced to the Paris Lodron University of Salzburg in 2020. Within the framework of this format members of the rectorate discuss certain key issues with employees of the PLUS, students and public representatives. The discussions take place LIVE and offer participants the opportunity to ask questions on current topics.
    On Wednesday 17th March 2021 PLUS is holding a virtual open day and warmly invites all interested pupils and final year classes offenen. Further information can be found under www.uni-salzburg.at/openday.
    After talks with the ministry and intensive consultation with the deans, the rectorate of the Paris Lodron University of Salzburg has decided that exams should generally only be conducted online at the moment. The following points apply here:
    There are numerous challenges in everyday elementary education, not only in Corona times. The art lies in dealing constructively with challenging situations. The fourth day of elementary education in Salzburg on 22nd January 2021, which will take place in digital form due to the pandemic-related measures, is dedicated to the topic of "Dealing with challenges in a solution-oriented way - competently and safely".
