The present invention provides a kind of hetero-junctions devitrified glass with photocatalysis performance, it is characterised in that：For Bi 3.64 Mo 0.36 O 6.55 /Bi 2 MoO 6 Hetero-junctions devitrified glass.It is prepared as follows (1), by Bi 2 O 3 And MoO 3 With molar ratio for 1:1 ratio carries out ball milling mixing and obtains uniformly mixed powder, is warming up to 650-750 DEG C of calcining for being put into furnace after uniformly mixed powder drying, then cools to grinding at room temperature with the furnace and obtain Bi 2 MoO 6 Crystal powder A；(2), the powder A and Li that will be prepared 2 B 4 O 7 With molar ratio for 3:7 ratio is uniformly mixed, and is poured into crucible, is warming up to 1000-1200 DEG C of calcining；Then melt is poured into water water quenching, after drying, grinding obtains Bi 3.64 Mo 0.36 O 6.55 Devitrified glass powder；(3), the Bi that will be prepared 3.64 Mo 0.36 O 6.55 Devitrified glass powder is poured into crucible and is heat-treated at 450-550 DEG C, so that devitrified glass crystal inside be made to grow up, obtains the devitrified glass with photocatalysis performance.The Bi with good photocatalysis performance has successfully been made 3.64 Mo 0.36 O 6.55 /Bi 2 MoO 6 Hetero-junctions devitrified glass. |
