Cars are equipped with catalysts to disarm toxic exhaust gases. Platinum plays an important role there. Leiden physicists and chemists have now for the first time seen the mechanism behind a platinum catalyst. With a fundamental understanding of the process, scientists can use this rare material more…

Electrochemist Marc Koper has won a special award: the Allen J. Bard Award in Electrochemical Science. 'Allen Bard has always been a great example to me, so it is extra special to win this award.' The award will be granted by the Electrochemical Society, at their half-yearly conference next year in…

A discovery made in Leiden helps not only to make natural gas from CO2 but also to store renewable energy. Research by Professor Marc Koper and PhD student Jing Shen shows how this process can be implemented in a cost-effective and controllable way. Nature Communications, 2 september 2015.

Professor of Catalysis and Surface Chemistry Marc Koper has been appointed as member of the Koninklijke Nederlandse Akademie van Wetenschappen (KNAW). 'Very honourable, I see this as a confirmation of my work,’ says Koper.

Smooth platinum electrodes roughen and wear when subjected to repeated cycles of oxidation and reduction, which causes nanometer-scale mounds to grow. Leiden chemists Leon Jacobse and Marc Koper, together with physicist Marcel Rost, discovered the exact details, using a unique tunneling microscope.

Density functional theory (DFT) with so-called semi-local exchange has been remarkable accurate for some dissociative chemisorption reactions on metals, but it has notoriously failed for others. A team of researchers from the University of California at Irvine and the Leiden Institute of Chemistry have…

If you could convert CO2 into building blocks for other molecules with the help of electricity, you could make the chemical industry considerably more sustainable. Leiden chemists have unravelled a fundamental part of this process and applied this knowledge in a real device, as they write in Nature…

Bringing together chemists and physicists to thoroughly investigate how electrochemical processes work on the smallest scale. That is the goal of the new Advanced Nano-electrochemistry Institute of the Netherlands, or ANION for short. The consortium receives a Gravitation funding of 23.6 million euros…

Scientists have long been puzzled why it is easier to produce hydrogen from water in an acidic environment than in an alkaline environment. Marc Koper comes with an explanation: the reason is the electric field at the surface of the catalyst, which is larger in an alkaline environment, as he writes…

Studying surfaces of solid materials: it may not seem relevant to energy consumption, but it is. Marcel Rost studies how platinum electrodes wear out. Those electrodes are a crucial component in the fuel cells of hydrogen-powered cars. ‘We need to make the switch from fossil fuel energy to hydrogen.…

The Leiden Institute of Chemistry actively participates in several national research schools for MSc and PhD students. These schools are consortia that stimulate collaboration between research groups of the different participating Dutch universities. The research schools also offer advanced training…

Dana Rademaker has won the Unilever Research Prize, which she received together with 2,500 euros at the Unilever’s Foods Innovation Centre on 12 December. She received the prize for her master’s thesis, which she wrote last year for the master’s programme Chemistry.

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

This dissertation combines the use of defined microenvironments, high-resolution fluorescence microscopy, and time-resolved analysis, to study intracellular and cellular motility.

Storing energy is one of the biggest challenges in the energy transition. Hydrogen could be a solution. Chemist Daan den Boer is researching how to make the chemical reaction needed to store energy in hydrogen as cheap and efficient as possible.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…
