Interfacial nanodroplets guided construction of hierarchical Au, Au-Pt, and Au-Pd particles as excellent catalysts.

摘要: Interfacial nanodroplets were grafted to the surfaces of self-sacrificed template particles in a galvanic reaction system assist construction 3D Au porous structures. The interfacial formed via direct adsorption surfactant-free emulsions onto particle surfaces. discretely distributed at and served as soft templates guide formation self-variation footprint sizes during growth gave rise hierarchical pore size distribution obtained particles. This strategy could be easily extended synthesize bimetal such Au-Pt Au-Pd. Au, Au-Pt, Au-Pd showed excellent catalytic activity reduction 4-nitrophenol.
