- Herein, we demonstrate that quantum-sized Ru dot decorated ultra-thin anatase TiO₂ nanosheets with exposed (001) facets could exhibit highly efficient catalytic activity during the conversion of levulinic acid to γ-valerolactone at room temperature. The support effect has been largely attributed to the high energy of TiO₂ (001) which can lead to a stronger interaction between the support and the metal. The surface of Ru/TiO₂-n contains more Ru(0) and results in higher activity and selectivity.
