Aqueous synthesis of nanosheet assembled tin oxide particles and their N2 adsorption characteristics

Tin oxide particles were synthesized in aqueous solutions. They consisted of nanosheets of tin oxide crystals. The sheets were about 50-100 nm in size and 5-10 nm thickness. X-ray diffraction analysis revealed that the particles were crystals of SnO2 and SnO. The particles had Brunauer-Emmett-Teller(BET) surface area of 85 m(2)/g estimated with N-2 adsorption characteristics. Barrett-Joyner-Halenda (BJH) analysis indicated that mesopores of 3.9 nm in size contributed to the increase surface area. (C) 2008 Elsevier B.V. All rights reserved.
