Abstract
In the rapidly developing areas of nanotechnology, nano-scale materials as heterogeneous catalysts in the synthesis of organic molecules have gotten more and more attention. In this review, we will summarize the synthesis of several new types of noble metal nanostructures (FePt@Cu nanowires, Pt@Fe2O3 nanowires and bimetallic Pt@Ir nanocomplexes; Pt-Au heterostructures, Au-Pt bimetallic nanocomplexes and Pt/Pd bimetallic nanodendrites; Au nanowires, CuO@Ag nanowires and a series of Pd nanocatalysts) and their new catalytic applications in our group, to establish heterogeneous catalytic system in “green” environments. Further study shows that these materials have a higher catalytic activity and selectivity than previously reported nanocrystal catalysts in organic reactions, or show a superior electro-catalytic activity for the oxidation of methanol. The whole process might have a great impact to resolve the energy crisis and the environmental crisis that were caused by traditional chemical engineering. Furthermore, we hope that this article will provide a reference point for the noble metal nanomaterials’ development that leads to new opportunities in nanocatalysis.
Highlights
Catalysis is the driving force behind the development of the chemical industry, which can make us use natural resources more efficiently, and reduce the pollution in the processes of the chemical industry
Certain achievements have been made in the metal nanomaterials as heterogeneous catalysts [7,8,9,10]
This review article reviews noble metal nanomaterials as heterogonous catalysts applied into organic reactions and electro-catalysis in our group recently, which intends to combine nanomaterial preparation and organic chemistry or fuel cell systems to find new catalysts for low-cost, highly-selective chemical synthesis that is clean and energy-efficient
Summary
Catalysis is the driving force behind the development of the chemical industry, which can make us use natural resources more efficiently, and reduce the pollution in the processes of the chemical industry. Nanocatalysts for catalytic chemical reactions mainly include the oxidation reaction [7], the reduction reaction [8], coupling reaction [9,10] and the electrochemical reaction [11,12,13,14,15] They have attracted more and more workers’ attention. This review article reviews noble metal nanomaterials as heterogonous catalysts applied into organic reactions and electro-catalysis in our group recently, which intends to combine nanomaterial preparation and organic chemistry or fuel cell systems to find new catalysts for low-cost, highly-selective chemical synthesis that is clean and energy-efficient. We introduce several platinum (Pt)-based nanocomplexes’ synthesis including FePt@Cu nanowires (NWs), Pt@Fe2O3 NWs and Pt@Ir zigzag bimetallic nanocomplexes The former two kinds of novel NWs were used as “non-support” heterogeneous catalysts in oxidation, while the latter one exhibited good performance in reduction. We attempt to point out a novel solution of “green chemistry” based on heterogeneous nanocatalysts, in order to stimulate the future development of nanomaterials that contributes to addressing the current challenges and that leads to new opportunities in nanomaterials and nanocatalysis
