The goal of this project is to perform an in-situ structural, morphological and compositional characterization of bimetallic electrocatalytic nanoparticles (NPs) both at the nanometer and the atomic scale.
A lot of economically valuable chemicals are obtained in industry through oxidation and reduction reactions. While many of these processes are highly exothermic, liberating energy as heat, they generally do not reach high energy efficiencies because most of this liberated energy cannot be recovered efficiently. Fuel cells offer the possibility to produce these chemicals through electrochemical reactions while converting the released energy into electricity, thus offering a clear advantage over the conventional production process.
Microfluidic technology involves the manipulation of fluids (gas or liquid) in channels with
dimensions lower than 1 mm, typically between 10-100 μm. Over the past 25 years, it has
grown into a mature field. Because of the small channel dimensions, chemical process
operations like mixing, reactions, dosing, and analyses have acquired substantial efficiency
gains. However, one aspect remains underdeveloped: general techniques that enable
Organic electrosynthesis is a field within electrochemistry that concerns the synthesis of organic products using the electron as a redox agent instead of chemical reductants or oxidants. It offers several important advantages to conventional synthetic methods, such as mild process conditions as reactions can be carried out at ambient temperature and pressure, higher selectivity due to precise control of the reaction by control of the electrode potential, ability to produce unstable or hazardous reagents in situ and less generation of pollutants and waste streams
Fundamental advances in energy conversion and storage which are full of vigor in meeting outfaces of some environmental phenomena such as waste water pollution and impact of fossil fuels are held by electrosynthesis. In the past decade organic electrosynthesis has become an interesting, versatile and environmental friendly alternative compared to classical organic synthesis.
Electrocatalysis is the linchpin of several modern electrochemical applications ranging
from energy storage devices over electroanalytical sensors to organic electrosynthesis.
Over the past decades electrocatalysis has grown to be a full-fledged part of heterogeneous
catalysis, supported by state-of-the-art theoretical insights.
Oxidation and reduction reactions are widely used in chemical industry for the
production of chemicals. As many of these processes are highly exothermic, a lot of
heat is produced. Because this heat cannot be fully recovered the processes often
have a low energy e_ciency.
Climate change and global warming pose an imminent global threat to our society and are directly
linked to the rising CO2 levels in the earth’s atmosphere. Since the energy sector is an important
contributor, significant impact is to be achieved in the transition from fossil-based towards renewable
energy like solar or wind power.
The rise in atmospheric greenhouse gas concentration has been linked to a global warming of 1.0 ± 0.2 °C since pre-industrial times. The need for negative emissions to prevent a global warming superior to 1.5 °C has increased the attractiveness of carbon dioxide (CO2) capture and utilization technologies.
Carbon-Hydrogen bonds are the most common bonds that occur in organic chemistry, they’re generally very strong, and unreactive. Because of the high dissociation energy associated with C-H bond activation ( the C-H bond dissociation in alkanes is 2.2-2.7 (V vs SHE)), molecules already containing functional groups will have them react at lower potentials, rendering late stage C-H functionalization useless. Chemical C-H activation is difficult to achieve, especially with C(sp3)-H bonds, it is expensive and associated with generation of a lot of waste.
