主权项

1. A mesoporous TiO2, comprising:
a substantially pure anatase crystal lattice structure, wherein the lattice structure comprises: grains of a size of about 10 nanometers (nm) to about 50 nm, wherein:
the grains form particles of a size of at least about 0.8 micrometers (μm); pores of a size of about 5 nm to about 25 nm; a tap density of about 0.6 g/cm3 to about 0.9 g/cm3; and a surface area of about 135 m2/g to about 180 m2/g.
