Highlights: • The complex SnO{sub 2} nanoparticles and nanosheets have grown by a hydrothermal method. • The concentration of urea can control the morphology of SnO{sub 2} nanostructures. • The complex SnO{sub 2} nanoparticles and nanosheets exhibit high photocatalytic activity. • The novel structures exhibit higher photodegradation than ZnO and TiO{sub 2} nanopowders. - Abstract: The complex SnO{sub 2} nanoparticles and nanosheets have been synthesized by a facile hydrothermal method. The concentrations of urea play an important role to control the morphology of SnO{sub 2} nanostructures. The complex SnO{sub 2} nanoparticles and nanosheets have excellent photocatalytic activity, which are ascribed to stronger defect emission, higher light harvesting ability in the visible light region, and higher surface-to-volume ratio, which exhibit a much better photocatalytic activity rather than commercial ZnO and TiO{sub 2} nanopowders under a blue light LED irradiation. The complex SnO{sub 2} nanoparticles and nanosheets provide a facile, low cost, high surface-to-volume ratio, high efficiency and stability visible-light-driven photocatalysts for environmental remediation and energy conversion.
