A new sustainable approach towards preparation of sunlight active Ag/AgBr Janus nanoparticles using non-toxic surface active ionic liquid

Abstract

The development of benign and easily implementable methods for preparation of symmetry controlled nano-materials for catalytic applications under sunlight or white light is a challenging task. A single step strategy and utilization of minimal chemicals under aqueous conditions under sunlight represents the first example of its kind. Herein, photocatalytically active Ag/AgBr Janus nanoparticles (JNPs) are prepared by irradiation of aqueous AgNO3 containing nicotinium based non-toxic surface active ionic liquid (SAIL) having Br as a counter-ion under sunlight, in less than a minute, via controlled symmetry breaking, for the first time. The utilized SAIL not only provides the required Br but also acts as a stabilizing agent and aids in photo-reduction. Thus the prepared JNPs exhibit excellent catalytic activity for photo-degradation of rhodamine-B under sunlight along with reduction of 4-nitrophenol.
