For the first time, Tin oxide (SnO₂) multiple branched nanowires (NWs) have been synthesized by thermal evaporation of tin (Sn) in presence of oxygen without use of metal catalysts at low substrate temperature of 500°C. Synthesized product consists of multiple branched nanowires and were single crystalline in nature. Each of the nanowire capped with catalyst particle at their ends. Energy dispersive X-ray analysis on the nanowires and capped nanoparticle confirms that Sn act as catalyst for SnO₂ nanowires growth. A self catalytic vapor–liquid–solid (VLS) growth mechanism was proposed to describe the SnO₂ nanowires growth.
