State-of-the-art biosynthesis of tin oxide nanoparticles by chemical precipitation method towards photocatalytic application.

Tin oxide (SnO) with versatile properties is of substantial standing for practical application, and improved features of the material are demonstrated in the current issue through the integration of nanotechnology with bio-resources leading to what is termed as biosynthesis of SnO nanoparticles (NPs). This review reveals the recent advances in biosynthesis of SnO NPs by chemical precipitation method focused on distinct methodologies, characterization, and reaction mechanism along with a photocatalytic application for dye degradation. According to available literature reviews, numerous bio-based precursors selectively extracted from biological substrates have effectively been applied as capping or reducing agents to achieve the metal oxide NPs.
