Synthesis, structure and photocatalytic properties of �?-ZrMo2O8

[摘要] Monoclinic ZrMo₂O₈ was synthesized via solid state method and single crystals of the title compound have been grown by the hydrothermal method. The crystals belong to monoclinic crystal system with space group 𝐶2/c (No. 15) with ð‘�? = 11.4243(19) Ã�?, ð‘�? = 7.9297(6) Ã�?, ð‘�? = 7.4610(14) Ã�? and ð›�? = 122.15(2)°, ð‘�? = 4. The bandgap of the compound was 2.57 eV. Unlike the other polymorphs of ZrMo₂O₈, the monoclinic form has unique crystallographic features with ZrO₈ and Mo₂O₈ polyhedra. The photocatalytic activity of this compound has been investigated for the first time for the degradation of various dyes under UV irradiation and has been compared with the photoactivity of the trigonal form of ZrMo₂O₈. It has been observed that this compound exhibits specificity towards the degradation of cationic dyes.
