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)-O-center dot radicals.
