Organizations often announce their protest activities prior to their implementation to mobilize awareness, recruit supporters, and receive media attention. We are interested in the effectiveness of protest announcements—that is, under what conditions governments make concessions to avoid having an announced…

Understanding the proces of electrochemical reactions is essential to improve the technology for the energy transition. Fuel cell cars, for example use hydrogen produced from the electrolysis of water. Mariana Monteiro did fundamental research on the process and won two prizes with her thesis.

An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…

Electrolysis is a technique that can be used to convert CO2 into fuels and other useful products. To do this efficiently and on a large scale, however, we need to understand exactly how electrolysis works. Professor Marc Koper is an expert in this field.

In the Catalysis and Surface Chemistry group, we investigate how catalysis works on the molecular level. The group is divided in six subgroups, focusing on different aspects of heterogeneous catalysis, homogeneous catalysis and electrocatalysis.

A tax on CO2 emissions from products entering the EU offers unprecedented opportunities in the fight against global warming. That is the conclusion of research on which Leiden environmental scientist Hauke Ward collaborated. ‘A new world is opening up,’ Ward says. ‘But success hinges on how we involve…

How can we reduce CO2 emissions from industry? Leiden psychologists Emma Mors and Christine Boomsma are examining the public perception and acceptance around the capture and storage of carbon dioxide. This is part of the ALIGN CCUS European research programme.

The University's CO2 footprint has once again decreased. This is the conclusion of the 2022 Sustainability Report. The report also concludes that steps have been taken to integrate sustainability into Leiden University education and research.

Several techniques are explored for going beyond the born-oppenheimer static surface model for molecule-surface reactions.

More CO2 in the atmosphere is making food crops more calorific, less nutritious and potentially more toxic.

Bioenergy with carbon capture and storage (BECCS) is a promising method for removing carbon dioxide (CO2) from the atmosphere and simultaneously generating energy. Yet this method is controversial, as it may require a great deal of land and water. Researchers at Leiden University have now proposed a…

A catalyst: normally a substance that speeds up a chemical reaction, without adding molecules to this reaction. Scientists from the group of Prof. Marc Koper of Leiden University and Prof. Yang Shao-Horn of MIT now discovered that in specific reactions that need oxygen, catalysts called metal oxides…

Research at the Catalysis and Surface Chemistry group is comprised of the following research themes:

Imagine we could convert the greenhouse gas CO2 into synthetic fuels using sustainable energy. This would enable us to reduce the amount of CO2 and at the same time store wind and solar energy in an innovative way. Chemist Akansha Goyal (Leiden University) is conducting fundamental research to make…

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

To construct catalysts that can produce fuels from CO2 innumerable times, we need to learn much more about how catalysis works. Irene Groot is conducting groundbreaking research into catalysis at the atomic level.

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

Hydrogen peroxide (H2O2) generation via electrochemical oxygen reduction is a sustainable production method for this bulk chemical. However, the selectivity of molecular catalysts for electrochemical H2O2 generation has hardly been investigated in a systematic manner, and it is unknown if their stability…

Sustainable energy from wind and solar is most readily available near the sea.

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this population will result in an enormous increase in the demand for food, consumables, water…

Leiden University continued to reduce its carbon footprint in 2021 by being more careful with natural resources and making structural reductions to its energy consumption. This is what it says in the Sustainability Report 2021.

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

Leiden astronomers published two articles on more sustainable astronomy in a special section of the journal Nature Astronomy. Among other things, they calculate that their online conference EAS 2020 consumed three thousand times less carbon dioxide than the face-to-face edition a year earlier. They…

The "Van Marum Colloquia" are a collaborative lecture series between the LION and LIC institutes, focusing on fundamental and applied surface science.

The transition to new and renewable energy sources should be completed by 2050. Researchers in various disciplines at Leiden University are conducting unique research that will help us make this transition and reduce CO2 emissions.

Hydrogen can help to solve the climate problem. At least, if we start producing it in the right, clean way. Leiden researchers mapped out the global environmental impact of hydrogen production and looked ahead to 2050. They published their work in Energy & Environmental Science.

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…
