Abstract. Transition metal oxides (Ti, V, Mo, Cr, etc.) incorporated within the framework of zeolites were found to exhibit high and unique photocatalytic reactivity as single-site heterogeneous catalysts for various reactions such as the decomposition of NOx (NO, N2O) into N2 and O2, the reduction of CO2 with H2O to produce CH4 and CH3OH, the preferential oxidation of CO in the presence of…
Abstract. Fe3+ bipyridine complexes were successfully anchored on the inner surface of the mesopores of SBA-15 and compared with those immobilized on the surface of SiO2. FT-IR, ESR, and XAFS measurements were used to characterize the structure of the formed μ–oxo-bridged binuclear Fe bipyridine complexes inside the mesopores of SBA-15, which were observed to be the active species for th…
Abstract. Cerium dioxide was prepared by the precipitation method and found to be an efficient photocatalyst to degrade azodyes under visible light irradiation. Nonbiodegradable azodyes acid orange 7 (AO7) was selected asmodal target to examine the photocatalytic activity of CeO2. AO7 could be efficiently degraded in aqueous suspension of CeO2 under visible light illumination. The catalyst …
