An unusual Cd-substituted sandwich-type polyoxomolybdate cluster {Mo20Cd2} for photocatalysis of organic pollutant

• {Mo20Cd2} consists of two [Mo10O32(ttb)]4 − moieties sandwiched by two Cd(II) atoms.
• Compound 1 displays an emission peak at 520 nm (λex = 320 nm).
• Compound 1 shows photocatalytic activities for degradation of organic dyes.

An unusual Cd-substituted sandwich-type polyoxomolybdate cluster {Mo20Cd2}, namely, [Cd(H2ttb)(H2O)Mo10O32(ttb)]2·3H2O (1) has been synthesized under hydrothermal condition (ttb = 1,3,5-tris(1,2,4-triazol-1-ylmethyl)-2,4,6-trimethyl benzene). Its structure has been determined by single crystal X-ray diffraction analysis and further characterized by elemental analysis, IR and TG. In 1, two decademolybdates are functionalized by ttb organic groups, which are further linked into a sandwich-type polyoxometalate cluster {Mo20Cd2} via two [Cd(H2O)(H2ttb)]4 + cations. The solid state photoluminescent property of 1 was investigated at room temperature. In addition, its photocatalytic performance for methylene blue (MB) has also been studied under UV irradiation.

An unusual Cd-substituted sandwich-type polyoxomolybdate cluster {Mo20Cd2} has been successfully synthesized under hydrothermal condition, where its photocatalytic performance for methylene blue (MB) has been studied under UV irradiation.Figure optionsDownload as PowerPoint slide
