摘要: Abstract A unique in-situ approach for synthesis of polymeric nanocomposites (pNCs) with Au nanoparticles (AuNPs) resulted in producing highly efficient nanocatalysts decomposition 4-nitrophenol, which base guaranteed convenient, multiple re-use. In-situ involved preparation the matrix, its modification by amines, and reduction-coupled adsorption AuCl4−. The was successfully applied production pNCs. It obtaining facile, efficient, extremely easy to use nanocatalysts. Based on research, matrix bearing functionalities derived from 1-amino-4-methylpiperazine (AMPp) allowed effectively load AuNPs at a concentration 15.5 %. These were characterized defined morphology average diameter 4.51 ± 2.11 nm. This optimal catalyst, linking relatively small size high AuNPs, exhibited excellent catalytic activity towards reduction 4-NP 4-AP mass-normalized rate constant 1.46 mg min-1.
