Fig. 8. Catalysis using nanoparticles (NPs) prepared via living CDSA methods. (A) Schematic illustration of PCL crystallization and binding of platinum and iron oxide NPs to generate catalytically active and magnetically recoverable nanostructures. (B) Coaxially electrospun polystyrene and patchy micelles formed by CDSA which contain gold nanoparticles. SEM images (1) showing micelle coverage can be analysed with a back scattered electron detector which shows the gold NP as bright dots (2). (C) Schematic illustration of living CDSA of PFDMS BCPs with catalyst and photosensitizer moieties attached to the corona-forming block to give catalytically active nanofibers capable of hydrogen generation from water in the presence of visible light. Panel (A) reproduced from ref. 271. Panel (B) reproduced from ref. 272. Panel (C) reproduced from ref. 273.
