Green synthesis of silver nanoparticles from green algae (Botryococcus braunii) and its catalytic behavior for the synthesis of benzimidazoles

Abstract

Abstract Nanoparticles are latest developing technology and received prodigious interest because it is simple, ecofriendly, pollutant free, non-toxic, and low-cost approach. In this report we demonstrated the synthesis of silver nanoparticles using green algae (Botryococcus braunii) which in turn used for synthesis of biologically important benzimidazoles. Algal extract was prepared and then mixed with silver nitrate solution for the synthesis of silver nanoparticles. Synthesized nanoparticles were characterized by UV, FTIR, X-ray and SEM. The synthesized silver nanoparticles were used as catalyst for one pot synthesis of 2-aryl benzimidazoles.
