摘要

Abstract

Mesoporous aluminum-doped titanium dioxide(Al-TiO

) materials with high specific surface areas were prepared

via

a solid-state reaction route.The properties of these materials were characterized by X-ray diffraction(XRD)

high resolution transmission electron microscopy(HRTEM)

energy dispersive spectroscopy(EDS)

absorption-desorption

ultraviolet visible light spectroscopy(UV-Vis) and electrochemical spectroscopy.The results show that the mesoporous structure of the product with ethanol is composed of anatase laced crystal walls with amorphous grain boundaries formed gradually by degradation.Compared with those without ethanol

these samples possess larger crystallite size since ethanol decreases the pore size at higher temperature.With the increase of ethanol amount

however

the crystallite size will grow.The amorphous grain boundaries in the mesoporous material

with a large impedance and low incidental cyclic potential

are difficult to effectively degrade and the phase transformation temperature is changed from 500 to 550℃.The growth rate of Al-TiO

crystallites that obeys the quadratic polynomial equation may be controlled.
