A novel self-assembling nanoparticle of Ag–Bi with high reactive efficiency

Abstract

A novel Ag–Bi nanoparticle has been prepared via a facile precipitation approach. The nanoparticle could achieve purification of contaminated water without supplements and exhibited much higher activity compared to other popular nanoparticles (e.g. nZVI). The excellent performance of Ag–Bi was due in part to a large production of ˙OH radicals.
