Projektbeschreibung
Effizientere Energieträger für eine nachhaltige chemische Industrie
Die chemische Produktion ist für einen großen Anteil der Bruttowertschöpfung der EU verantwortlich. Jedoch ist die chemische Industrie sehr energieintensiv – 95 % der organischen chemischen Erzeugnisse werden aus fossilen Ölen und Erdgas gewonnen. Um ein nachhaltiges Wachstum zu garantieren, muss die chemische Industrie fossile Rohstoffe durch erneuerbare Kohlenstoff-, Phosphor- und Siliziumquellen ersetzen. Aktuell gibt es keine effizienten Energieträger für die Verwendung dieser oxidierten Ausgangsstoffe. Das EU-finanzierte Projekt ReNewHydrides entwickelt innovative recycelbare Reduktionsmittel auf Basis von Silizium- und Borverbindungen, um katalytische Herausforderungen bei der Reduktion von C-O-, P-O- und Si-O-Verbindungen sowie der Valorisierung von Kunststoffabfällen, CO2, CO und mehr anzugehen. Die Arbeit des Projekts wird neue nachhaltige Methoden zur Verwendung erneuerbarer Ausgangsstoffe fördern.
Ziel
The production of chemicals, plastics, solvents, etc., contributes to 20 % of the Gross Value Added in the EU, where sales have doubled over the last 20 years. Despite this dynamism, the chemical industry is energy intensive and 95 % of organic chemicals derive from fossil oil and natural gas. To sustain the growth of this industry, the replacement of fossil feedstocks with renewable carbon, phosphorus and silicon sources should be encouraged. Nonetheless, such a sourcing shift represents a paradigm shift: while the development of petrochemistry has relied on the selective oxidation of hydrocarbons, the conversion of renewable feedstocks (e.g. CO2, phosphates, silicates or biomass) requires efficient reduction methods and catalysts to overcome their oxidized nature.
Today, no reduction method meets the criteria for a versatile and energy efficient reduction of oxidized feedstocks and the aim of the ReNewHydrides project is to design novel reductants and catalytic reactions to achieve this important aim. At the crossroads of main group element chemistry, organometallic chemistry, electrochemistry and homogenous catalysis, I propose to develop innovative and recyclable reductants based on silicon and boron compounds, and to utilize them to tackle catalytic challenges in the reduction of C–O, P–O and Si–O bonds. The overarching principle is to build a balanced synthetic cycle, where the electrochemical reduction of functionalized and oxidized substrates is ensured by silicon and boron based hydride donors, with a high energy efficiency and selectivity.
This project will foster innovative routes in the utilization of renewable carbon, phosphorus and silicon feedstocks. It is therefore of high risk, but ultimately extremely rewarding. The results will also also open-up new horizons in silicon and boron chemistry and they will finally serve the scientific community involved in the fields of organic and inorganic chemistry, sustainable chemistry and energy storage.
