A New Approach to Synthesize Nano-Sized SnO2 Via Low Temperature Solid-State Reaction

Abstract

This study presents a novel method for quickly preparing nanoscale SnO₂ materials through a low-heat solid-state reaction. This method utilizes SnSO₄ and H₂O₂ disinfectant powder (H₂O₂ as a reactive substance) as raw materials. When the mixed powders were heated to 90 °C, a rapid reaction occurred, which resulted in the formation of SnO₂. X-ray diffraction results showed that the prepared SnO₂ material was amorphous, The powder exhibited good dispersion, and SnO₂ nanoparticles were approximately 20 nm in size. X-ray photoelectron spectroscopy results revealed that the sample surface was rich in hydroxyl. Finally, a reaction mechanism for preparing nanoscale SnO₂ materials through a solid-state reaction was proposed.
