Gold-based nanoalloys: synthetic methods and catalytic applications

Dendrimer-encapsulated nanoparticles: New synthetic and characterization methods and catalytic applications

In this article we describe the synthesis, characterization, and applications of dendrimer-encapsulated nanoparticles (DENs). These materials are synthesized using a template approach in which metal ions are extracted into the interior of dendrimers and then subsequently reduced chemically to yield nearly size-monodisperse particles having diameters in the 1–2 nm range. Monometallic, bimetallic...

Synthetic applications of gold-catalyzed ring expansions

The development of new methodologies catalyzed by late transition metals involving cycloisomerizations of strained rings can open new venues for the synthesis of structurally complex molecules with interesting biological activities. Herein we summarize, from both a synthetic as well as a mechanistic point of view, the most recent developments in gold-catalyzed ring expansions.

Gold-palladium core@shell nanoalloys: experiments and simulations.

In this work, we report a facile synthesis route, structural characterization, and full atomistic simulations of gold-palladium nanoalloys. Through aberration corrected-STEM, UV-vis spectroscopy and EDS chemical analysis, we were able to determine that Au(core)-Pd(shell) bimetallic nanoparticles were formed. Using different computational approaches, we were capable of establishing how the size ...

Synthetic advancements and catalytic applications of nickel nitride

Transition metal carbides and nitrides have received a large amount of attention in chemistry and materials science due to their interesting properties and potential to substitute precious metal catalysts. Earthabundant early transition metal carbides and nitrides were the primary focus of many efforts, while late transition metal alternatives are less explored. This brief review discusses rece...
