Supported silver catalysts prepared via melt infiltration: Synthesis, characterization and performance in selective hydrogenation

Heterogeneous supported catalysts are often synthesized by impregnation or precipitation methods. Recently, melt infiltration has emerged as an alternative method that allows high metal loadings and eliminates the need for a solvent, but challenges arise regarding control over particle size distribution. In this work, synthesis of silver is explored. The narrow pore distribution chosen ordered mesoporous silica support, SBA-15, allowed in depth in-situ ex-situ characterization precursor, molten nitrate, into support its subsequent decomposition to form metallic nanowires nanoparticles. heat treatment parameters during played key role determining whether nanoparticles were formed. containing weight investigated selective hydrogenation cinnamaldehyde, where showed superior activity selectivity Hence, shows great promise loadings, which applicable in, e.g., oxidation reactions.
