Tin Oxide Nanoparticles via Solar Vapor Deposition for Hexavalent Chromium Remediation.

ABSTRACT: Tin oxide nanoparticles optimized to capture low concentrations of hexavalent chromium from water were developed through a facile, scalable, and low-cost one-step solar vapor deposition methodology. Considering the preservation of high electron donation capacity as the key to support the reduction of mobile Cr(VI) into insoluble forms, the growth of SnO nanoparticles was favored by the co-evaporation of SnO₂ with Fe powders at various mass ratios. Characterization techniques indicated that the percentage and the stability of SnO is proportional to the Fe content in the target with a requirement of at least 50% wt to inhibit the formation of a passive SnO₂ surface layer. The produced particles were evaluated regarding their efficiency to capture Cr(VI) under conditions
