    Abstract: The conversion efficiency of existing photocatalysts may decrease with increasing humidity level. The photocatalyst of this invention is made be first mixing an alcohol, a titanium alkoxide and a binder in the presence of a catalytic acid to form a mixture. This mixture is then heated at about 100° C. for at least 2 hours, and then calcinated at about 450° C. for at least 2 hours. The resulting catalyst is found to have improved efficacy at high humidity level.
