Phase transformation-induced crystal plane effect of iron oxide micropine dendrites on gaseous toluene photocatalytic oxidation
Source abstract
Abstract
Abstract Hematite (α-Fe 2 O 3 ), magnetite (Fe 3 O 4 ), and maghemite (γ-Fe 2 O 3 ) micropine dendrites were synthesized by a facile hydrothermal method and oxidation-reduction process. The samples have been thoroughly characterized by various physicochemical techniques. The adsorption ability, quantum efficiency, and the photo-induced charge separation of the electron–hole pair in the samples were demonstrated by the XPS, FTIR, UV–vis, and PL spectroscopy. The α-Fe 2 O 3 showed higher catalytic activity than the other two samples for photocatalytic oxidation of gaseous toluene. This may be attributed to the phase transformation-induced crystal plane effect of the α-Fe 2 O 3 micropine dendrite, which has relatively more reactive crystal planes {0 0 1} and {1 1 0} exposed on the surface of α-Fe 2 O 3 .
