Facile Synthesis of Morphology-Controlled Platinum Nanocrystals

摘要

Morphology-controlled synthesis of nanostructures is a great challenge in materials chemistry because the morphology (including dimensionality and shape) of most nanostructures can effectively tune their intrinsic chemical and physical properties.Nanostructured platinum is an example of considerable interest for many industrial applications because of its extraordinary properties.For example,it serves as a catalyst in the production of hydrogen from methane,in the reduction of pollutant gases exhausted from automobiles,and particularly in the direct methanol fuel cell (DMFC).It has been established that the catalytic reactivity of platinum nanostructures highly depends on the morphology of the nanoparticles,and therefore the design and synthesis of well-controlled shapes and sizes of platinum nanoparticles could be critical for their application,especially in the field of catalysis.
