Shape control of platinum and palladium nanoparticles for catalysis
TLDR
This minireview surveys the different approaches in solution-phase synthesis that have been successfully adopted for achieving shaped platinum and palladium nanoparticles that are enclosed with specific crystallographic facets.Abstract:
Platinum and palladium are important catalysts for a wide variety of industrial processes. With the increasing demands of these materials, the development of high-performance catalysts is an important area of research, and as a result, shape control synthesis has become one of the leading research focuses. This minireview surveys the different approaches in solution-phase synthesis that have been successfully adopted for achieving shaped platinum and palladium nanoparticles that are enclosed with specific crystallographic facets. In addition, catalytic studies of the shaped nanoparticles are highlighted, in which promising results have been reported in terms of enhanced activity and selectivity. The future outlook discusses the aspects in synthesis and catalysis to be considered for the development of highly efficient and effective catalysts.read more

Observation of Single Colloidal Platinum Nanocrystal Growth Trajectories
TL;DR: In this article, the authors used in situ transmission electron microscopy to show that platinum nanocrystals can grow either by monomer attachment from solution onto the existing particles or by coalescence between the particles.

Biogenic Synthesis of Metallic Nanoparticles by Plant Extracts
TL;DR: The use of plant biomass or extracts for the biosynthesis of novel metal nanoparticles (silver, gold, platinum, and palladium) would be more significant if the nanoparticles are synthesized extracellularly and in a controlled manner according to their dispersity of shape and size as discussed by the authors.

Size and Shape Control of Metal Nanoparticles for Reaction Selectivity in Catalysis
Kwangjin An,Gabor A. Somorjai +1 more
TL;DR: In this article, a colloidal synthetic approach is used to control the size and shape of nanoparticles, which enables it to be studied as a model heterogeneous catalyst. But, the size of metal particles can be controlled to cluster regimes by using dendrimers.
