Chemistry for the future online!
It is our great pleasure to invite you to this year’s ARC CBBC Annual Symposium. With our online programme we aim to inspire our community and everyone who is connected to chemistry.
Our Scientific Director prof. Bert Weckhuysen will welcome you at 13.45 h. Throughout the Symposium, you will be inspired by our young generation of researchers. We are honoured that prof. Erik Paredis from Ghent University will join our symposium to share insights into the politics of a circular and carbon-neutral economy in the opening lecture. During the closing lecture our Chair, the renowned prof. Ben Feringa, will reflect on chemistry for the future.
The Chemical Building Blocks Consortium (ARC CBBC) is a unique partnership in which leading international chemical companies and universities join forces to fundamentally change production for a sustainable future. New value chains will lower our CO2 footprint, accelerate the circular economy, and provide the base materials for products that we use in everyday life.
We look forward to seeing you on September 24th!

Programme Annual Symposium 2020
13.45 – 14.00
Welcome by Prof. Bert Weckhuysen (UU/Scientific Director)
14.00 – 14.15
Opening lecture by prof. Erik Paredis (UGent)
The Politics of a Circular and Carbon-Neutral Economy: The Challenge of Going Beyond Science-Industry-Driven Framings
Erik Paredis is associate professor “Transition governance and socio-technical system innovation for the circular economy” at the Department of Political Sciences, where he teaches the courses “Politics of Sustainability” and “Sustainability Thinking”.
One of the main challenges our societies are facing over the next decades, is the development of a carbon-neutral and circular economy. Technological innovation will be an important element in that transformation, and science and industry are working hard to be part of the solution. We are currently witnessing a fast growth in (proposals for) technological innovations in the energy and chemical sector, ranging from CCU(S), hydrogen and synfuels to circular plastics. Although often presented as neutral techno-scientific innovations, such transitions are inextricably bound up with questions of social arrangements and institutions, power and exclusion, procedural and distributive justice, as well as normative, societal preferences. Given the huge societal implications of current technological research and evolutions, they demand processes in which the voices and expertise of a broad range of stakeholders and disciplines is heard. A purely science and industry-driven framing does not do justice to the just transition for which e.g. the EU Green Deal is striving.

Dr. Eline Hutter (UU/Tenure Track ARC CBBC)
Opportunities and Challenges of Metal Halide Perovskites for Solar Energy Conversion
Metal halide perovskite (MHP) semiconductors have received tremendous attention in materials science due to their excellent optoelectronic properties. As a result, MHPs were successfully used in highly efficient solar cells, X-ray detectors and LEDs and more recently also recognized for their photocatalytic activity. MHPs are relatively simple to process, and their composition can be easily changed so that the absorption and emission properties can be tuned. Therefore, MHPs offer great potential for solar energy conversion applications. However, in order to maximize efficiencies, a detailed understanding of decisive processes is needed, such as the generation of charges on light absorption, charge transport and charge transfer to e.g. an electron acceptor. In this talk, dr. Hutter will present how a combination of time-resolved spectroscopic techniques and kinetic modelling can be used to get insight into these processes. Dr. Hutter will show how this approach, for instance, enabled us to conclude that holes can get efficiently transferred from MHPs, while electrons are slowly immobilized into trap states. Finally, she will address the toxicity concerns of lead-based perovskites, and present some preliminary results on the transport properties of silver-bismuth perovskites.

Dr. Marta Costa Figueiredo (TU/e/Tenure Track ARC CBBC)
Electrocatalysis – a Pathway for Sustainable Chemicals
Many industrial chemical processes involve a high-energy demand (often still derived from fossil fuels), toxic reactants, and the production of high amounts of waste. Therefore, the development of more efficient, less hazardous technologies, based on renewable energies, has become one of the most challenging topics for chemical synthesis. For achieving these goals, the combination of catalysis with electrochemical methods, that is, electrocatalysis, can play a very important role. With electrochemical methods, toxic and dangerous chemicals can be replaced with clean electrons, the efficiency and selectivity of the reactions can be tuned by choosing the applied potential, and more importantly, the energy used can come from renewable sources like wind or solar. In this talk, dr. Costa Figueiredo will focus on how electrocatalysis can help on the knowledge generation, reaction improvement and development of alternative industrial processes. She will give examples from studies of the electrosynthesis of high-value chemicals such as organic carbonates, fuels and energy-dense carriers.

Reinventing Chemistry Together
Chemistry, being the creating science par excellence, is facing major fundamental challenges on our route to design the circular processes and sustainable materials of the future. The Advanced Research Centre – CBBC, is focusing on a long-term program developing these new chemistries in a collaborative set-up of leading universities and industry. Challenges, opportunities and perspectives for the ARC-CBBC will be briefly discussed.
The symposium is chaired by our ARC CBBC PhD students Sophie van Vreeswijk (UU) and Lotte Metz (UvA).
The Symposium will take place digitally. Details will be sent to the participants closer to the date.
