The invention discloses a method for synthesizing a
rutile TiO2
nanowire array by
soft chemistry and hydrothermal technology. The method has the characteristics of low preparation temperature, simple application technology, large specific surface area and high
photo catalytic activity of the obtained photocatalyst, and the
rutile serving as a main body.
Hydrochloric acid,
toluene,
titanium tetrachloride, and tetrabutyl
titanate are weighed according to a certain ratio, the
toluene is used as a
solvent, and solution of
titanium tetrachloride and solution of tetrabutyl
titanate are prepared respectively. The method for preparing the TiO2
nanowire array comprises the following steps of: (1) cleaning a
glass slide which is cleaned by solution of
ethanol into an ultrasonic cleaner for several minutes, and cleaning the
glass slide by using deionized water; (2) weighing a certain amount of tetrabutyl
titanate and
titanium tetrachloride according to the stoichiometric ratio respectively, and dissolving the tetrabutyl titanate and
titanium tetrachloride in a certain amount of solution of
toluene respectively; (3) putting the cleaned
glass slide into a sealed reaction kettle which is made of stainless steel and has a white
polytetrafluoroethylene lining, and adding a certain amount of
hydrochloric acid; (4) guiding the flow by using a glass rod, slowly adding a certain amount of solution of toluene, tetrabutyl titanate, and
titanium tetrachloride; (5) putting the reaction kettle into a
drying oven for heat treatment, wherein the
reaction temperature is between 130 and 180 DEG C, and the reaction time is 6 to 22 hours; and (6) naturally cooling the reaction kettle at
room temperature, and taking the glass slide out, and
drying so as to obtain the TiO2
nanowire array.
