Atomically dispersed noble metal catalysts often exhibit high catalytic performances, but the loading density must be kept low (usually below 0.5%) to avoid formation of nanoparticles through sintering. We report a photochemical strategy fabricate stable atomically palladium-titanium oxide catalyst (Pd1/TiO2) on ethylene glycolate (EG)-stabilized ultrathin TiO2 nanosheets containing Pd up 1.5%. The Pd1/TiO2 exhibited activity in hydrogenation C=C bonds, exceeding that surface atoms...
Improving Reactions at Interfaces Alloying precious metals such as platinum with more abundant transition metals, iron and nickel, can both improve their catalytic reactivity lower catalyst cost. Chen et al. (p. 495 ) explored using coatings of oxide–hydroxide layers on supported nanoparticles for CO oxidation. The presence this layer allowed the reaction to run rapidly room temperature by bringing together different sites two metals. addition nickel improved lifetime, an oxidative...

A variety of metallic nanoparticles with a narrow size distribution have been synthesized in facile one-phase method which amine-borane complexes are applied as reducing agents. It is particularly striking that large colloidal crystals sizes up to tens micrometers can directly form from the reaction mixtures without any further treatment. By using synthetic route described, large-scale syntheses both mono- and alloyed be easily achieved.
High-index surfaces of a face-centered cubic metal (e.g., Pd, Pt) have high density low-coordinated surface atoms and therefore possess enhanced catalysis activity in comparison with low-index faces. However, because their energy, the challenge chemically preparing nanocrystals having high-index facets remains. We demonstrate this work that introducing amines as controller allows concave Pt {411} to be prepared through facile wet-chemical route. The as-prepared display unique octapod...
