Scientists have created a catalyst consisted of deficient concentrations of platinum on the surface of titanium dioxide. They showed how this catalyst significantly improves the rate of breaking a particular carbon-oxygen bond for the conversion of a plant derivative into biofuel.
Their strategy—defined in a paper published in Nature Catalysis on Mar. 23—could be utilized to design stable, lively, and selective catalysts primarily based on a variety of metals supported on metallic oxides to provide industrially helpful chemicals and fuels from biomass-derived molecules.
Aromatic rings are structures with atoms joined by single or double bonds. In molecules obtained from plant waste, aromatic rings usually have oxygen-containing facet teams. Reworking plant waste derivatives into helpful products require the removal of oxygen from these facet teams by breaking specific carbon-oxygen bonds.
In this research, the scientists hypothesized that including noble metals to the surfaces of moderately reducible metal oxides—those that may lose and gain oxygen atoms—would promote hydrodeoxygenation.
To test their speculation, the team chosen platinum as the noble steel and titanium dioxide (titania) as the metal oxide. Theoretical measuremetns and modeling indicated that the formation of oxygen vacancies is extra energetically favorable when single atoms of platinum are launched onto the surface of titania.
