At present, a vast majority of products such as plastics, cosmetics or pharmaceuticals are still petroleum-based. A shift towards renewable bio-based feedstock will be inevitable in the future. However, the use of biomass for chemical production implicates the redesign of existing processes and involves new challenges. Handling of aqueous reaction systems and the need for adapted separation tec...

Plasmon-driven sequential chemical reactions were successfully realized in an aqueous environment. In an electrochemical environment, sequential chemical reactions were driven by an applied potential and laser irradiation. Furthermore, the rate of the chemical reaction was controlled via pH, which provides indirect evidence that the hot electrons generated from plasmon decay play an important r...
