The results showed that a Fe2O3 and SnO2 were present in the composites. The characterization results found that the phase composition, crystallite size, BET surface area and optical absorption of the samples varied significantly with the molar ratio of Sn to Fe. The Fe2O3-SnO2 photocatalyst (the molar ratio of Fe to Sn is 2: 1) calcined at 550 degrees C for 5 h exhibited maximum photocatalytic activity because it has a smaller band gap and a higher surface area of 120 m(2) g(-1). Under visible-light irradiation, the degradation efficiency of nitric oxide reached 95.0 %, which is ca. 1.72 times higher than that of the nanoparticles SnO2 (Aldrich).  ISSN : 0970-7077  Journal Name : ASIAN JOURNAL OF CHEMISTRY  Volume : 25  Issue Number : 17  Publishing Year : 1434 AH 2013 AD  Article Type : Article  Added Date : Sunday, July 16, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email E Baeissa Baeissa, E Researcher     Files File Name Type Description  42029.pdf pdf   Back To Researches Page
