Bimetallic Platinum-Tin Nanoparticles on Hydrogenated Molybdenum Oxide for the Selective Hydrogenation of Functionalized Nitroarenes

Catalyst Development for Selective Hydrogenation of Functionalized Alkynes and Nitroarenes

Polymer-functionalized platinum-on-gold bimetallic nanorods.

Physical and chemical properties of nanosized crystals are known to be a function of their size, morphology, and chemical composition. Hence, over the past decade many research groups have focused on controlling the shape of inorganic nanostructures, and many low-symmetry nanocrystals have been produced. In this respect, one-dimensional structures are particularly interesting objects whose opti...

A PdAg bimetallic nanocatalyst for selective reductive amination of nitroarenes.

Herein we have identified an optimal catalyst, Pd1Ag1.7, for the tandem reductive amination between nitroarenes and aldehydes (selectivity > 93%). Key to the success is the ability to control the compositions of the investigational Pd1-xAgx (x = 0-1) catalysts, as well as the clear composition dependent activity/selectivity trend observed in this study. This catalyst features a wide substrate s...

Combination of supported bimetallic rhodium–molybdenum catalyst and cerium oxide for hydrogenation of amide

Hydrogenation of cyclohexanecarboxamide to aminomethylcyclohexane was conducted with silica-supported bimetallic catalysts composed of noble metal and group 6-7 elements. The combination of rhodium and molybdenum with molar ratio of 1:1 showed the highest activity. The effect of addition of various metal oxides was investigated on the catalysis of Rh-MoO x /SiO2, and the addition of CeO2 much i...

Synthesis of Bimetallic Platinum Nanoparticles for Biosensors

The use of magnetic nanomaterials in biosensing applications is growing as a consequence of their remarkable properties; but controlling the composition and shape of metallic nanoalloys is problematic when more than one precursor is required for wet chemistry synthesis. We have developed a successful simultaneous reduction method for preparation of near-spherical platinum-based nanoalloys conta...
