Precious metals such as platinum, palladium, gold, rhodium or iridium can be found in a variety of everyday products, for example in catalytic converters of cars, in mobile phones and laptops as well as in solar cells. They are particularly interesting for chemists because of their low reactivity with other elements. A team of researchers, led by Professor Ulrich Kortz at Jacobs University Bremen, now wants to develop a new class of materials containing precious metals and investigate their possible applications. “These materials will be very exciting not only for catalysis, but also for quantum computers and data storage,” says Prof. Kortz. The project is funded by the German Research Foundation with around 200,000 euros.

To make it to the final was his goal. “I’m really happy that it worked out,” says Jan Felix Schuster. The 19-year-old qualified for the national finals of the youth competition ‘Jugend forscht’ in Chemnitz from 16 to 19 May. He is the state champion of Bremen in the field of chemistry, and participating is more important than winning for him. “Getting to know the other projects and making new contacts is what I enjoy most about ‘Jugend forscht‘”.
Medicine? Yes! Engineering? Yes! But chemistry? Better not. “When people in Zimbabwe say that they want to study chemistry, most people ask: ‘What will you do with it?’ “, tells Lisa Tichagwa. “They normally suggest other subjects.” The 21-year-old nevertheless decided to study chemistry at Jacobs University Bremen. Now she has been awarded the August Wilhelm von Hofmann scholarship of the German Chemical Society (GDCh) for her outstanding academic achievements – and she feels satisfied with her choice. “The scholarship shows me that I made the right decision.”

It is stable and recyclable: a team of scientists from Jacobs University led by Ulrich Kortz, Professor of Chemistry, has developed a new class of materials in close cooperation with researchers from the Carl von Ossietzky University of Oldenburg and the Technical University of Munich. The compound based on the precious metal palladium paves the way for the full use of the entire class of discrete polyoxopalladates (POPs) as building blocks for 3D framework materials (MOFs). The project was funded by the German Research Foundation (DFG). The name of the new class of materials: POP-MOF, JUB-1.
The palladium(II)-containing 40-tungsto-4-arsenate(III) [Pd2Na2KAs4W40O140(H2O)]21– was synthesized by reaction of PdSO4 with the cryptate heteropolyanion [As4W40O140]28– in potassium acetate buffer. The title compound was characterized by single-crystal XRD, IR, TGA, and elemental analysis.
