Light-Catalyst Interactions to Sense and Steer Chemical Reactions

AMOLF and Utrecht University have been awarded a 1.9 million euro research project by the Dutch Research Council (NWO) Key Technologies 2020-2023 programme to develop radically new catalytic reactors using plasmonic systems. The project entitled “Sensing and Steering Catalytic Reactions with Light” (CatLight) is a multidisciplinary collaboration between AMOLF (Alarcon-Llado, Albrecht, Ehrler, Garnett and Polman), Utrecht University (Weckhuysen, Hutter, Rabouw), and industrial partners BASF, ExxonMobil, Shell, Toyota Motor Europe, DENSsolutions, and Delmic.

The focus of the CATLight research project is to gain fundamental understanding and to develop new technologies that deliver targeted heat in industrially relevant catalyst systems with unprecedented spatio-temporal accuracy. This will create a promising new platform for efficient catalysis by using light and nanophotonic concepts.

The new optically-driven catalysis technology will thus contribute to create more sustainable ways to efficiently drive important chemical reactions. The smarter use of energy and active thermal management enabled by photonic architectures developed in this research project will represent a paradigm shift for modern catalysis towards sustainable chemistry research.

Research plans
The consortium will demonstrate an entirely new way to make commercially relevant catalytic processes more active, selective and energy efficient. It will do so by combining the mature control over light-matter interactions at AMOLF, the unique in-situ and operando spectroscopy for investigating catalytic processes at Utrecht University and the know-how of the chemical and analytical industry partners . CatLight introduces the use of intense light pulses to steer chemical reactions at the catalytically active sites that are locally heated by absorption of optical radiation at plasmonic nanoparticles. A 3D network of optical waveguides decorated with plasmonic nanoreactors guides intense light pulses to the catalytically active sites and is embedded in a reaction vessel. Simultaneously, optical excitation provides key thermal and spectroscopic fingerprints of the reactive species involved in the chemical pathways as they proceed in space and time.

Natural phenomena ‘hyperuniform disorder’ enables highly efficient, thin silicon solar cells

Silicon solar panels are rigid and heavy, and many rooftops cannot support them. This creates a need for thin, flexible solar cells that can be integrated into building materials. However, making silicon solar cells thinner makes it harder to trap light inside the material. Researchers in the 3D Photovoltaics group found a fascinating way to overcome this challenge using a phenomenon called hyperuniform disorder. They publish their findings in the journal ACS Photonics.

The researchers were able to make highly efficient silicon solar cell materials that are 30 times thinner than conventional ones. They managed to do this by integrating a layer of nanometer sized structures on top of the material. Up close, this pattern looks random, but it is remarkably when you step back: no clumps, no gaps, and no repeating pattern. This is called hyperuniform disorder (or HUD).
