Researchers at the University of Helsinki have made a breakthrough in sustainable molecular transformations by developing materials and processes that can leverage the power of visible light to drive chemical processes more efficiently. Led by Professor Pedro Camargo, their work, published in ACS Applied Materials and Interfaces, offers a greener alternative to traditional methods of producing essential chemicals and fuels. The team focused on overcoming barriers such as cost and scalability by using materials readily available on Earth in significant quantities, such as HxMoO3 and palladium, in a solventless mechanochemical synthesis technique.
Their research explores the impact of shining specific wavelengths of visible light on their catalyst, which led to a significant increase in its performance. By using two wavelengths of light concurrently, they achieved a remarkable 110% increase in reaction efficiency. This was attributed to the optimized generation of energetic electrons at catalytic sites, representing a significant advancement in sustainable catalysis. The team identified the synergistic effects of HxMoO3 band gap excitation, Pd interband transitions, and HxMoO3 localized surface plasmon resonance, which led to enhanced catalytic performance.
Professor Camargo believes that their work is a major step towards making chemical processes more sustainable by utilizing light as an energy source, potentially revolutionizing the production of vital chemicals and reducing the reliance on fossil fuels and harsh industrial conditions. This research has vast applications in cleaner fuel production and manufacturing essential materials with less environmental impact. It offers hope for a greener, more sustainable future as society seeks to combat climate change and transition towards renewable energy sources.
The team’s focus on materials that are abundant on Earth and their innovative use of visible light for catalysis represent a significant contribution to sustainable chemistry.
