Polymere Mizellen …︁…︁ werden von Y. Yamauchi, B. P. Bastakoti et al. in ihrer Zuschrift auf S. 11225 ff. für die Herstellung gut dispergierter mesoporöser Pt‐Nanokugeln verwendet. Ein Kern/Schale/Kranz‐Triblockcopolymer [Poly(styrol‐b‐2‐vinylpyridin‐b‐ethylenoxid), PS‐b‐P2VP‐b‐PEO] wird als porenbildendes Reagens eingesetzt. Die negativ geladenen PtCl42−‐Ionen wechselwirken bevorzugt mit den protonierten...
A facile method for the fabrication of well‐dispersed mesoporous Pt nanospheres involves the use of a polymeric micelle assembly. A core–shell–corona type triblock copolymer [poly(styrene‐b‐2‐vinylpyridine‐b‐ethylene oxide), PS‐b‐P2VP‐b‐PEO] is employed as the pore‐directing agent. Negatively charged PtCl42− ions preferably interact with the protonated P2VP+ blocks while the free PEO chains prevent...
