Hybridization of CuO and AlPO4 framework to produce a novel nanoporous material of CuO-AlPO4
Global warming and CO2 decomposition are interconnected, as CO2 is a major contributor to global warming. One potential approach to mitigating global warming is decomposing CO2 to release oxygen into the atmosphere. In order to decompose the CO2, we have synthesized CuO-AlPO4 by using tetrapropylammonium hydroxide as a template. It is characterized by XRD, FT-IR, BET, TGA, TPD and TEM analyses. XRD results proved that the novel structure of CuO-AlPO4 is formed with two crystal systems, creating a hybrid framework. Aluminophosphate is in a tetrahedral framework and in CuO, the Cu2+ ions are coordinated in a linear way with tetrahedral oxygen (O2−). So, there is a charge transfer transition between O2− and Cu2+ ions, which is proved by UV–Vis spectra. The formation of this hybrid framework may be influenced by the orientation of the template molecules. The hybridization of the frameworks facilitates the generation of oxide ions (O2−), which are highly active in decomposing CO2 at a lower temperature compared to previous literature. The maximum CO2 conversion and oxygen selectivity achieved are 98% and 91%, respectively.
