Solvent-Free Synthesis and Applications of Highly Dispersed Ruthenium Catalysts Prepared by Solid-Phase Mixing.

ABSTRACT: Solvent-free catalyst synthesis provides significant environmental benefits and simplifies the synthesis process. In this study, we utilized the interaction between metal oxide and support to prepare highly dispersed and active Ru catalysts using a simple, solvent-free method. Bulk ruthenium dioxide was physically mixed with six kinds of solid oxide supports (Al₂O₃, SiO₂, TiO₂, tetragonal ZrO₂, monoclinic ZrO₂, and CeO₂), followed by thermal treatment in air at 773-1273 K. Ru K-edge X-ray absorption fine structure analysis of the treated samples showed that atomically dispersed Ru species were obtained at 973-1073 K when monoclinic ZrO₂ and CeO₂ were used as supports. In contrast, RuO_2</
