Abstract
In the rapidly developing areas of nanotechnology, nano-scale materials as heterogeneous catalysts in the synthesis of organic molecules have got more and more attentions. In this review, we will summarize the synthesis of a new type of ultrathin nanostructure via wet chemical method and several new catalytic applications to establish heterogeneous catalytic system in “green” environments. Further study shows that these materials have higher catalytic activity and selectivity than previously reported nanocrystal catalysts. This review intends to combine nanomaterials preparation and organic chemistry to find new catalysts for low-cost, efficient, highly selective chemical synthesis. The catalytic transformation of functional groups based on novel nanomaterials, can achieve not only "atoms economy", but also the chemical processes show low energy consumption and induce low pollution at the same time. The whole process might have a great impact to resolve the energy crisis and the environmental crisis, which was caused by the traditional chemical engineering.
The main contents of the review include: 1) synthesis of ultrathin metallic nanostructures; 2) important catalytic molecule activation and the functional group transformation process at interface in the nano-catalyzed process; 3) understanding the effect of crystal structure of the nano-catalysts on the catalytic activity; 4) point out a novel solution of "green chemistry" based on non-supported nanocatalyst.
Keywords: Platinum nanowires, catalysis, hydrogenation, dehydrogenation.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
