摘要: Excellent catalytic reduction of 4-NP in aqueous solution was achieved under ambient condition using nickel (Ni) nanoparticles generated PMMA@PHEMA polymeric micelles. Ni were formed two different micelles, namely Ni-loaded PMMA10K@PHEMA5K and PMMA12K@PHEMA34K which resulted the distinctive differences content as well sizes nanoparticles. Besides concentration catalyst, rate depended on micelle structure, i.e., higher activity observed for PMMA10K@PHEMA5K. More importantly, performance markedly improved with increasing amount PHEMA-shell crosslinker despite a
