“…The reports on the catalytic applications of activated carbon-supported ruthenium, palladium, and iridium complex or nanoparticle composites in TH were frequently found. In particular, these easily fabricated, even commercially available, materials were extensively used in the synthesis of fine chemicals, fuels, and functional compounds, such as methyl furan, , dimethyl furan, , monoenes, hexitols, citronellal, aromatic heterocycle-containing amines, quinazolin-4( 3H )-one and benzimidazoles, and halogenated anilines …”
