Macroporous TiO2 monolith was prepared by a microphase separation method. After citric acid was added to the synthesis procedure, the yield of the titanium precursor has been significantly increased, and the stability of macroporous structure can be obviously enhanced. Anatase and rutile phase of TiO2 were obtained after a 550 °C and 800 °C calcination, respectively.
