This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

This thesis focuses on the synthesis, characterization and performance towards CO2 electroreduction of mono and bi-metallic particles based on p-block metals

Carbon dioxide capture and utilization technologies are necessary to create a truly circular economy. The electrochemical reduction of carbon dioxide to formate is an appealing carbon utilization method as it can be performed at room temperature and pressure, it only requires two electrons, and it has…

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.

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

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.

Stel je voor: we kunnen met duurzame energie het broeikasgas CO2 omzetten in synthetische brandstoffen. Dan verminderen we én de hoeveelheid CO2, én we hebben een nieuwe manier om bijvoorbeeld wind- en zonne-energie op te slaan. Chemicus Akansha Goyal (Universiteit Leiden) doet fundamenteel onderzoek…

Waterstof kan het klimaatprobleem helpen oplossen. Tenminste, als we het op de juiste, schone manier gaan produceren. Leidse onderzoekers brachten de wereldwijde milieu-impact van waterstofproductie in kaart en keken vooruit tot 2050. Ze publiceerden hun werk in Energy & Environmental Science.

Een taks op de CO2-uitstoot van producten die de EU binnenkomen, biedt ongeziene mogelijkheden in de strijd tegen klimaatopwarming. Dat blijkt uit onderzoek waar de Leidse milieuwetenschapper Hauke Ward aan meewerkte. ‘Een nieuwe wereld gaat open’, zegt Ward. ‘Maar het succes staat of valt met hoe we…
