Monodisperse AuCuSn trimetallic nanocube catalysts.

Controlling and self assembling of monodisperse platinum nanocubes as efficient methanol oxidation electrocatalysts.

An efficient synthetic approach that enables not only the control of Pt nanocubes but also the one-pot fabrication of novel Pt nanocube assemblies was developed for the first time. The integration of well-defined building blocks and unique superstructures endows Pt nanocube assemblies with enhanced performance in the methanol electrooxidation, showing a new concept for further enhancing the per...

Comparison of bimetallic and trimetallic catalyst in reductive dechlorination; influence of copper addition

Efficiency of reduction of PCBs in aqueous solution was examined with the help of bimetallic catalyst Fe-C/Pd consisting of palladized grey cast iron and with a newly designed trimetallic catalyst (Cu-Fe-C/Pd) consisting of a copper metal plate with embodied microparticles of palladized grey iron (bimetallic catalyst). PCB solutions were prepared using DELOR 103. The trimetallic catalyst was si...

MoS₂ nanocube structures as catalysts for electrochemical H₂ evolution from acidic aqueous solutions.

Core-shell PMMA-Au nanocube structures made by a combination of nanoimprint lithography and sidewall deposition were used as template for electrodeposition of MoS2, Ni, and Pt. Linear sweep voltammetry experiments obtained in an aqueous solution containing 0.29 M H2SO4 (pH 0.24) showed that the onset potential of the core-shell-shell PMMA-Au-MoS2 nanocube electrode for the hydrogen evolution re...

Ghost in the Shell: Studies on Subsurface Oxygen in Oxide-Derived Copper Nanocube Catalysts

Trimetallic magnesium complexes bearing amine-bis(benzotriazole phenolate) derivatives as bifunctional catalysts for ring-opening polymerization and CO2/epoxide coupling.

New trimetallic magnesium complexes were synthesized for bifunctional catalysis. Complex catalysed ε-caprolactone polymerizations in not only a 'living' manner but also in an 'immortal' fashion. Additionally, tri-Mg was active for the coupling of CO(2) with cyclohexene oxide (CHO) on addition of n-Bu(4)NBr co-catalysts to give cis-cyclohexene carbonate under mild conditions.
