摘　　要：借助一步法,通过调变丙三醇的量制备分散性好、粒径均匀、尺寸可控的SnO2纳米颗粒.XRD、FESEM、UV-vis、TEM、XPS等研究结果表明:在含5.00 mL甘油体系下制备出的SnO2具有较高的结晶度,同时其分散性最好,孔容孔径最大,呈现最佳的光催化活性.This manuscript described a one-pot synthesis route for the fabrication of size-controllable tin dioxide（ SnO2 ） nanocrystals with good dispersity and uniform size. The characterization results based on XRD, FESEM, UV-vis, TEM and XPS indicate that the as-prepared sample in the presence of 5.00 mL glycerol exhibited the highest photocatalytic performance owing to its better crystallinity, good dispersity,largest porosity and pore size.
