Driven by the highly integrated impetuses of hydrolyzation,Ostwald ripening and structure-modification,nanostructured SnO2/α-Fe2O3 nanoheterojunctions with the morphologies of cone and hyacinthus orientalis have been prepared through a solvothermal method.Diverse structural and photochemical data of SnO2/α-Fe2O3 nanoheterojunctions provide strong evidence that both cone and hyacinthus orientalis demonstrated high reactivity of the photogenerated electron and hole owing to their excellent visible-light harvesting and electron transfer properties.In particular,with the intrinsic features,including bandgap,composition and morphology,cone exhibits a superior visible-light photocatalytic activity(98%MO degradation within 30 min),which is among one of the most efficient nanoheterojunction photocatalysts.This smart approach can stimulate further fundamental work on the chemical interface design in bulk heterojoint materials for superior photocatalytic performance.
