报告题目：Catalyst Development for Renewables Conversion with Renewable Energy
报 告 人：Prof. Dr. Harry Bitter（Wageningen University, Wageningen, The Netherlands）
Harry Bitter performed his PhD research at the University of Twente in the group of prof. Johannes Lercher (catalytic processes and materials) where he worked on dry-reforming of CH4 with CO2 to syngas. After his PhD Harry joined the Utrecht University as junior staff member where he continued working in the field of heterogeneous catalysis focusing on the use of X-Ray spectroscopy in catalysis. From 1999-2013 he was a scientific staff member at Utrecht University in the group of Inorganic Chemistry and Catalysis (group of Prof. Krijn de Jong). Since 2013 Harry is full professor at Wageningen University and Research. He is holding the chair of Biobased Chemistry and Technology. Within the chair he focuses on catalytic biobased conversions and (extraction) processes on multiple length scales using a multidisciplinary approach. Harry published about 163 papers h-index 54, is involved in 5 patent applications, and teaches courses in inorganic chemistry, catalysis, and biobased economy. In addition Harry is among others board member of the Royal Dutch Chemical Society (KNCV), board member of the Dutch Research School on Catalysis (NIOK) and chair of the educational committee of NIOK.
To ensure a sustainable future, our desired fuels, chemicals, and materials must be produced in an environmentally friendly manner. Utilizing renewable feedstocks, such as biofeedstocks, and relying on renewable energy allow us to address two critical aspects simultaneously. In this presentation, I will showcase our achievements in developing catalysts, primarily Pt on carbon-based materials, for the conversion of (poly)saccharide feedstocks like glucose and starch. I will demonstrate that surface polarity plays a pivotal role in determining the performance of the catalyst for both thermal-catalytic and electro-catalytic conversion over Pt on carbon nanofibers and Pt on activated carbon. Additionally, I will discuss the impact of pore size on catalyst performance. The presentation will highlight the significance of employing a combined experimental and modeling approach to gain new insights into catalyst performance. In that way understanding of the catalyst performance could be reached which will ultimately lead to more sustainable and efficient processes.
