Lanthanum-based catalysts for (bio)ethanol conversion: effect of preparation method on catalytic performance – hard templating versus hydrolysis

Valsamakis I. Garbarino G.

BACKGROUND: Lanthanum-based materials, namely La2O3 and La(OH)3, are of interest for several heterogeneous catalytic reactions because of their properties; that is, in spite of their poor resistance to CO2 and moisture, readily converting at room temperature to carbonates and oxycarbonates and requiring strong thermal treatments to revert back...

Ni/SiO2-Al2O3 catalysts for CO2 methanation: Effect of La2O3 addition

Riani P. Valsamakis I. Cavattoni T.

Ni-based catalysts, 13.5 Ni wt.%, with enhanced thermal stability and catalytic performance for CO2 methanation have been synthesized with different La2O3 loadings. Catalysts have been extensively characterised by: XRD, IR, H2-TPR, IPA-TPD, UV–vis-NIR, FE-SEM and tested in CO2 methanation. SiO2 addition to Al2O3 support decreases the activity...
