CoAPO-5-type molecular sieve membrane: synthesis, characterization and catalytic performance

Cobalt and/or manganese incorporated berlinites (CoMnAPO4) and aluminophosphate molecule sieve (CoMnAPO-5) were hydrothermally synthesized, characterized by XRD, FT-IR, XPS and SEM, and employed as catalysts in the oxidation of cyclohexane with molecular oxygen at 348 K under atmospheric pressure. It was found that the berlinite-based catalysts were more selective for the production of KA oil, stable during the reaction, but slightly less active for the conversion of cyclohexane, when compared to their molecular sieve counterparts. The CoMnAPO4exhibited a better catalytic performance, due to a synergic effect, than the CoAPO4or MnAPO4.

Xrd Patterns

Microporous aluminophosphate (AlPO-5) and titanium aluminophosphate (TAPO-5) molecular sieves, which are zeolite-like materials have been synthesized by direct hydrothermal method using two different templates; triethylamine (TEA) as organic base and tetraethylammonium hydroxide (TEAOH) as alkali base. XRD patterns confirmed that the TAPO-5 catalysts are identical with AFI structure but the crystallinity of the catalysts had decreased after the incorporation of titanium into the framework. Besides that, characterization of TAPO-5 catalysts using DRUV-Vis confirmed the coordination of titanium species and this evidenced also supported by the result 27Al MAS NMR. Catalytic performance of the TAPO-5 catalysts was tested in the oxidation of styrene to produce benzaldehyde and phenylacetaldehyde in the presence of hydrogen peroxide as oxidant. TAPO-5 catalysts showed higher activity in styrene oxidation compared to AlPO-5. Keywords: zeolite; aluminophosphate; titanium; organic template; styrene
