But at present all existing photocatalytic materials only have limited air purification efficiency with few purge gas types.
Based on the insufficiency of the existing technology, this experiment adopts a new idea, i.e. use materials such as halloysite and aluminum oxide to make porous ceramics as the wall materials and use nano WO3[2] doped La2O3 as a photocatalytic composite [3] to make a kind of absorbent purification material with a higher purification efficiency.
Fig. 1 Test Method for the Purification Efficiency of Porous Materials 2.
While Lanthanum oxide plays the role of stimulating photocatalytic materials to improve the catalytic activity of photocatalytic materials and promote the purification efficiency. 3.

The starting materials SiO2, Al2O3, CaO, BaCO3, Sb2O3, Na2CO3 and H3BO3 are all reagent grade chemicals.
Batches of well mixed starting materials; weighted to 50 g according to the formulas, were melted in the alumina crucibles at 1100 °C inside an electronic furnace.
Moreover, according to the classical dielectric theory, the refractive index depends on density and on polarizabilities of atoms in a given materials [11].
