The invention discloses a
quartz sand supported
lanthanum titanate photocatalyst. The
quartz sand supported
lanthanum titanate photocatalyst mainly comprises absolute ethyl
alcohol, absolute
methanol,
acetone,
titanium alkoxide, guiding agents,
lanthanum acetate,
ammonium acetate, glacial
acetic acid, butylene glycol and
quartz sand. A method for preparing the quartz sand supported
lanthanum titanate photocatalyst includes preparing precursors, to be more specific, adding the
titanium alkoxide and the guiding agents into the absolute ethyl
alcohol, the absolute
methanol and the
acetone to obtain
titanium alkoxide solution, forming lanthanum acetate solution from
distilled water, the lanthanum acetate, the
ammonium acetate and the glacial
acetic acid, adding the titanium alkoxide solution into the lanthanum acetate solution drop by drop and adding the butylene glycol into the lanthanum acetate solution to obtain final transparent solution; carrying out support and heat treatment, to be more specific, adding the quartz sand into the final transparent solution, arranging beakers in magnetic stirring constant-temperature water bath kettles, stirring the final transparent solution under the condition of the temperature of 50-90 DEG C to obtain light yellow gel,
drying the light yellow gel until the light yellow gel is dehydrated,
grinding the light yellow gel to obtain
powder, arranging the
powder in a program-control chamber electric furnace, heating the program-control chamber electric furnace at the
room temperature at the heating rate of 2-10 DEG C / min until the temperature of the program-control chamber electric furnace reaches a
calcination temperature, keeping the
calcination temperature unchanged for 1-10 h, cooling the
powder and then
grinding the powder to obtain materials. The quartz sand supported
lanthanum titanate photocatalyst and the method have the
advantage that the
pollutant photocatalytic purification capacity of
lanthanum titanate can be obviously improved.
