Silica-supported PdGa Nanoparticles: Metal Synergy for Highly Active and Selective CO2-to-CH3OH Hydrogenation

A precise synthesis of small (<2 nm) supported palladium-gallium alloyed nanoparticles on Ga^IIIsites dispersed on silica (PdGa@SiO₂) is reported. This material, prepared via a Surface Organometallic Chemistry (SOMC) approach, is highly active and selective in hydrogenation of CO₂ to methanol.

Electrophilicity in heterogeneous catalysis: Role of surface and sub-surface modification

Efforts to bridge the gap between homogeneous and heterogeneous catalysis include the use of surface organometallic chemistry, single atom catalysis and monodispersed metal nanoparticles, among others. In case of metal...

Heterogeneous alkane dehydrogenation catalysts investigated via a surface organometallic chemistry approach

Alkane dehydrogenation over heterogeneous catalysts has attracted renewed attention in recent years. Here, well-defined catalysts based on isolated metal sites and supported Pt-alloys prepared via SOMC are discussed and compared to classical systems.

Well-Defined Surface Tungstenocarbyne complex through the Reaction of [W(≡CtBu)(CH2tBu)3] with CeO2 : a highly and stable precatalyst for NOx reduction with NH3 ≡

A novel well-defined precatalyst for ammonia selective catalytic reduction of NOx (NH3-SCR), [W(CtBu)(CH2tBu)3]/CeO2, was prepared by surface organometallic chemistry and characterized. Due to the high dispersion of the active phase,...
