Technology

The molybdate complex described in this invention is formed in a single-step process from Ag2MoO4 and PPNCl. It has a structure of [PPN]2[MoO4] and is capable of binding up to 2 equivalents of CO2, giving rise to [PPN]2[MoO3(κ2-CO3)] and [PPN]2[MoO2(κ2-CO3)2]. The binding of the first equivalent of CO2 has been demonstrated to be stable up to 70 ℃ under a vacuum, while that of the second equivalent can be reversed even at low temperatures. This difference in stability is what allows this novel molybdate complex to be used when either reversible or irreversible CO2 binding is desired.
