Cathodic corrosion is a relatively unknown phenomenon that can severely etch metallic electrodes at cathodic (negative) potentials.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

This project aims at determining the market value of hydrogen peroxide (HP) that is produced via our electrochemical methods that have been developed as part of the ERC-StG Cu4Energy project.

The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

Warisa started as a Postdoc researcher at the Department of Environmental Biology of CML in March 2020.

Electrocatalysis will play an increasingly important role in future in the transition to more sustainable energy. Thanks to chemist Isis Ledezma Yanez, we now know more about the hydrogen evolution process. PhD defence on the 9th of June.

Research of the Leiden Institute of Chemistry into the development of a sustainable fuel cell has accidentally resulted in an exceptionally efficient catalyst for the production of hydrogen peroxide. The catalyst, discovered by Dennis Hetterscheid and PhD candidate Michiel Langerman, may lead to a more…

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…

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

Methods for accurately computing the interaction of molecules with metal surfaces are critical to understanding and thereby improving heterogeneous catalysis.

Leiden chemists Marc Koper and Ian McCrum have discovered that the degree to which a metal binds to the oxygen atom of water is decisive for how well the chemical conversion of water to molecular hydrogen takes place. This insight helps to develop better catalysts for the production of sustainable hydrogen,…

SMR can be used to measure the mass of adsorbed protein to nanoparticles with a high precision in the presence of free protein.

Electrocatalysis allows for storing electricity or converting it into chemical bonds, producing chemical building blocks and fuels using renewable resources.

Molecular complexes can be used as electrocatalysts for oxygen reduction, water oxidation, and/or hydrogen peroxide production.

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

Curved single crystals provide variable, but well-defined surface structures.

How does CO adsorption on gold promote its own oxidation and the oxidation of other organic molecules?

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.

We report new computational and experimental evidence of an efficient and astrochemically relevant formation route to formaldehyde (H2CO). This simplest carbonylic compound is central to the formation of complex organics in cold interstellar clouds and is generally regarded to be formed by the hydrogenation…

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.

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

Twenty years from now, the world population is estimated to be around 9 billion people (now 7.8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables, water and energy.…

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

Marc Koper’s research focuses on electrocatalysis and electrochemical surface science for sustainable energy and chemistry. Reactions of interest are the redox reactions of the oxygen/hydrogen cycle (water oxidation, hydrogen evolution), the carbon cycle (reduction of carbon dioxide, oxidation of small…

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

Radiation can be used to determine the isotope ratio of a skeleton. This provides information about where our ancestors lived and what they consumed. Dr Andrea Waters has developed a revolutionary method that can trace patterns of consumption from tens of thousands of years ago.
