One pot synthesis of nanoscale phase-segregated PdPt nanoarchitectures via unusual Pt-doping induced structural reorganization of a Pd nanosheet into a PdPt nanotent.
نویسندگان
چکیده
Pt-doping of an ultrathin Pd nanosheet results in the unprecedented structural rearrangement of a Pd nanosheet into a PdPt nanotent structure, in which a tripod stands on a triangular nanosheet. Further growth of Pt phase on this nanotent structure is dependent on the presence of surface-stabilizing CO molecules, leading to the formation of two distinct nanoscale phase segregated structures with respective structural features of a popped out Pt facet and an overgrown Pt layer.

PdPt bimetallic nanoparticles enabled by shape control with halide ions and their enhanced catalytic activities.
In this study, a new and convenient one step approach is described for synthesizing shape controlled PdPt bimetallic nanoparticles. It is found that the resultant morphologies of these PdPt nanoparticles can be well controlled by simply altering the participation of different halide ions that serve as shape controlling agents in the reaction solution. The dendritic core-shell PdPt bimetallic na...
متن کاملVapour and mechanically induced chromic behaviour of platinum complexes with a dimer-of-dimer motif and the effects of heterometal ions.
Heterodinuclear complexes, syn-[MPt(μ-pyt)2(bpy)2](n+) (syn-[MPt], M = Pd(2+), Au(3+), Hpyt = pyridine-2-thiol, bpy = 2,2'-bipyridine), were synthesized as a selective geometrical isomer by stepwise complexation. X-ray analyses of the hexafluorophosphate salts of these complexes proved their dinuclear structures with short M···Pt distances (2.9084(4) Å for syn-[PdPt] and 2.9071(4) Å for syn-[Au...
متن کاملبررسی خواص حسگری نانوهیبرید SnO2 و آلیاژ دوفلزی PdPt نسبت به گاز متان و تاثیر افزودن اکسیدگرافن کاهش‌یافته بر بهبود خواص حسگری آن
در این مقاله، خواص حسگری نانوهیبرید SnO2-PdPt نسبت به گاز متان و تاثیر افزوده شدن اکسید گرافن کاهش‌یافته بر بهبود خواص حسگری این نانوحسگر، مورد بررسی قرار گرفته است. برای این منظور، ابتدا به روش هیدروترمال SnO2 سنتز شد و سپس با کاتالیستهای Pd، Pt و PdPt هیبرید شد. برای بررسی اثر اکسید گرافن کاهش یافته بر بهبود خواص حسگری، به جای SnO2 از SnO2-rGO سنتز شده به روش هیدروترمال درجا، استفاده شد. نتای...
متن کاملHigh Performance Plasma Sputtered PdPt Fuel Cell Electrodes with Ultra Low Loading
A PdPt (10 wt% Pt) catalyst is used to replace platinum at the cathode of a PEMFC MEA whereas pure palladium is used as the anode catalyst. The catalysts are deposited on commercial carbon woven web and carbon paper GDLs by plasma sputtering. The relations between the depth density profiles, the electrode support and the fuel cell performances are discussed. It is shown that the catalyst gradie...
متن کاملAn experimental and theoretical investigation of the inversion of pd@pt core@shell dendrimer-encapsulated nanoparticles.
Bimetallic PdPt dendrimer-encapsulated nanoparticles (DENs) having sizes of about 2 nm were synthesized by a homogeneous route that involved (1) formation of a Pd core, (2) deposition of a Cu shell onto the Pd core in the presence of H2 gas, and (3) galvanic exchange of Pt for the Cu shell. Under these conditions, a Pd@Pt core@shell DEN is anticipated, but detailed characterization by in-situ e...
