Abstract
A novel 2-dimensional phosphomolybdate, (H3O)4{Zn2[Zn[H7Mo 6 V O15(PO4)4]2]} (1), which is a non-classical sandwich-type inorganic compound, has been synthesized and systematically characterized. As polyoxometalates often exhibit abnormal and confusing thermal decomposition performances because of the numerous constituent atoms and unique structures. High atomic ratios of P:Mo (8:12) in 1 can also lead to elusory thermal decomposition mechanisms and residues as a consequence of diversiform phosphomolybdenum compounds (MoP, MoP2, Mo4P3, etc.) and molybdenum oxides (MoO2, MoO3, etc.) with high boiling points. Consequently, the thermal decomposition performance of 1 was explored in this study and an underexplored substances, Mo8P5, was discovered in the thermal decomposition residues of 1. In addition, the photocatalytic properties of 1 were also studied and experiments showed that 1 was a suitable photocatalyst for degrading organic pollutants.
