摘要：
SnO2 nanocrystals grown on chrysotile surfaces could be facilely synthesized in large quantities through a direct precipitation process coupled with a calcination treatment. The as-synthesized chrysotile/SnO2 nanocomposites showed a smaller band gap energy (2.88 ev) and relatively strong light absorption than the individually dispersed SnO2 nanocrystals. Due to the narrow gap and chemical passivation aroused by inherently negative charges on the surface of chrysotile, chrysotile/SnO2 nanocomposite was endowed with superior performance to chrysotile nanotube and SnO2 nanocrystals.
