Despite the fact that both electrochem. experiments and d. functional theory calculations have testified to the superior electrocatalytic activity and CO-poisoning tolerance of PtRu alloy nanoparticles toward the MeOH oxidation reaction (MOR), the facet-dependent electrocatalytic properties of PtRu nanoparticles are scarcely revealed because it is extremely difficult to synthesize well-defined facets-enclosed PtRu nanocrystals. We, for the 1st time, report a general synthesis of ultrathin PtRu nanocrystals with tunable morphologies (nanowires, nanorods, and nanocubes) through a 1-step solvothermal approach and a systematic study of the structure-directing effects of different surfactants and the formation mechanism by control experiments and time-dependent studies. We use these {100} and {111} facets-enclosed PtRu nanocrystals as model catalysts to evaluate the electrocatalytic characteristics of the MOR on different facets. Remarkably, {111}-terminated PtRu nanowires exhibit much higher stability and electrocatalytic mass activity toward MOR, which are 2.28 and 4.32 times higher than those of {100}-terminated PtRu nanocubes and com. Pt/C, resp., indicating that PtRu {111} facets possess superior MeOH oxidation activity and CO-poisoning resistance relative to {100} facets. This work provides a series of well-defined PtRu nanocrystals with tunable facets which would be ideal model electrocatalysts for fundamental research in fuel cell electrocatalysis. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Recommanded Product: N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride).
N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Recommanded Product: N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride
