文摘
Uniform crystalline CdSnO3·3H2O nanocubes with a 28-35 nm edge length have been obtained via the ion-exchange reaction of Na2Sn(OH)6 in a CdSO4 aqueous solution, assisted by ultrasonic treatment. Precursor Na2Sn(OH)6 crystals were prepared via hydrothermal treatment in an ethanol/water solution. The formation ofCdSnO3·3H2O nanocubes resulted from the strain during the ion-exchange process. The influences of reactionconditions, such as ion-exchange (ultrasonic treatment) duration, solvent constitutes, surfactant, and pH on theformation of CdSnO3·3H2O crystals were described. Crystalline CdSnO3 and Cd2SnO4 have been obtained bythermal treatment at 300 and 500 
C, respectively, for 5 h under an inert-gas protecting condition using CdSnO3·3H2Onanocubes as the precursor. The cube shape of CdSnO3·3H2O was sustained after thermal decomposition toCdSnO3.
