Insights into the solvothermal reaction for synthesizing tin(iv) oxide porous spheres.The solvothermal synthesis of SnO2 porous spheres was optimized by varying the reactants, solvents, additives, reaction temperature and reaction time.  SnO2 possessing a highly ordered spherical structure based on the aggregation of nanometer-sized primary particles was obtained using a simple one-pot solvothermal approach.
