Tin(IV) oxide nanoparticles (SnO 2 NPs) have attracted great attention in various fields such as environmental remediation, sensing, catalysis, and lithium ion batteries. This led to an intense development of different synthetic pathways for production of SnO 2 NPs. At present, production of SnO 2 NPs depends largely on methods that involve toxic chemicals and harsh reaction conditions, which have been identified as a major drawback and potential threats to human health and the environment. Alternatively, green synthesis has gained popularity, as it is eco-friendly and cost-effective and generates minimal waste. This paper focuses on green biosynthesis of SnO 2 NPs using various plants and their different plant parts, including an evaluation of their potential applications. This work also emphasizes the effects of plant extracts and solvents on the size, morphology, and other properties of the synthesized SnO 2 NPs.

A large number of mesoporous materials have been synthesized by using supramolecular assembly of ionic/non‐ionic surfactants as structure‐directing agents (SDAs). Here, we report a facile synthetic strategy to fabricate self‐assembled SnO2 nanoparticles with well‐defined nanocrystalline spherical morphology and mesoporosity using sodium salicylate as a SDA and stabilizing agent. The mesophases of the materials were investigated by powder XRD, TEM and N2 sorption studies. TEM results show that the mesopores are formed by the assembly of ultrasmall SnO2 NPs with broad range of interparticle void spaces. This synthesis strategy facilitated the generation of SnO2 NPs with increased surface area and pores of nanoscale dimensions with a large number of exposed surface active sites. The photoinduced electron transfer in these materials was investigated by the fluorescence quenching study with pyranine, which suggested the presence of surface Lewis basicity. The materials showed excellent catalytic activity for the synthesis of β‐nitroaldol through the reaction of benzaldehyde and nitromethane. The heterogeneous nature of the catalyst could be attributed to the high surface area, presence of numerous surface active sites, and structural robustness of the self‐assembled SnO2 nanostructure. The catalysts exhibited negligible loss in activity after several catalytic cycles.
