Nano-scale characterization of catalytic metal nanoparticle -semiconductor interfaces using in situ Atomic Force Microscopy
Are you the Master student who is passionate about physical and chemical properties of solid-liquid interfaces in the context of a variety of application areas including wetting, friction and lubrication, carbonate mineralization, and photo- and electrocatalysis.? Read below for further details!
he Physics of Complex Fluids PCF, aims to provide fundamental understanding of the physical and chemical properties of solid-liquid interfaces in the context of a variety of application areas including wetting, friction and lubrication, carbonate mineralization, and photo- and electrocatalysis.
In the latter context, the present PhD project focuses on AFM-based spectroscopy to characterize the interfaces between electrolyte, semiconductor- and cocatalyst-nanoparticles under photocatalytic operating conditions (i.e. in liquid, under applied bias and illumination) and to establish correlations between local surface properties such as atomic scale structure, charge density, and hydration and the resulting photocatalytic activity. To elucidate the catalytic performance at the nanoscale, conductive and electrochemical AFM will be used. These methods should reveal correlations between topographic and catalytic activity via current mapping, and identify the underlying charge transport mechanism via local IV-spectroscopy. Using this suite of AFM-based methods, the ultimate goal of the project is to generate insights how nanoscale surface properties affect the overall catalytic performance of photo/electrochemically active catalytic nanoparticles.
This information should eventually provide guidance in the development of novel more efficient materials for the desired redox reactions, such as water splitting or CO2 reduction.

About the department
Our faculty focuses on three domains, namely Chemistry, Health, and Physics. We are the home base for the research institutes TechMed, MESA+, the Techno Centre for Education and Research (TCO), and the Twente Graduate School (TGS). TNW offers six Bachelor's and seven Master's programs in Health Sciences, Nanotechnology, (Applied) Physics, Chemistry, and Technical Medicine. Over 850 colleagues and 2,700 students are active within the faculty of Science & Technology.
About the organization
The Faculty of Science & Technology (Technische Natuurwetenschappen, TNW) engages some 700 staff members and 2000 students in education and research on the cutting edge of chemical technology, applied physics and biomedical technology. Our fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine. As part of a people-first tech university that aims to shape society, individuals and connections, our faculty works together intensively with industrial partners and researchers in the Netherlands and abroad, and conducts extensive research for external commissioning parties and funders. Our research has a high profile both in the Netherlands and internationally and is strengthened by the many young researchers working on innovative projects with as doctoral candidates and post-docs. It has been accommodated in three multidisciplinary UT research institutes: Mesa+ Institute, TechMed Centre and Digital Society Institute.
