Resumen:
This work analyzes the deposition conditions of thin layers of γ-Al2O3 by dip-coating on a spherical substrate of α-Al2O3 spheres. Results showed that under controlled deposition conditions, a structured support of α-Al2O3 spheres coated by an uniform γ-Al2O3 layer (thickness≈15 μm) of good adherence, can be attained. Optimal preparation conditions for the coating, that involved pretreatment of the substrate, gel formation, deposition conditions and thermal treatments, were obtained.Pt samples supported on this structured material can be used as promising ehydrogenation catalysts. In this sense, a monometallic structured catalyst showed both good metallic dispersion and catalytic performance in n-butane dehydrogenation reaction compared toanother conventional catalytic system.
